Introduction 106 This document defines a YANG data model for IS-IS routing protocol. 108 The data model covers configuration of an IS-IS routing protocol 109 instance as well as operational states. 111 1.1. Tree diagram 113 A simplified graphical representation of the data model is presented 114 in Section 2. 116 The meaning of the symbols in these diagrams is as follows: 118 o Brackets "[" and "]" enclose list keys. 120 o Curly braces "{" and "}" contain names of optional features that 121 make the corresponding node conditional. 123 o Abbreviations before data node names: "rw" means configuration 124 (read-write), and "ro" state data (read-only). 126 o Symbols after data node names: "?" means an optional node and "*" 127 denotes a "list" or "leaf-list". 129 o Parentheses enclose choice and case nodes, and case nodes are also 130 marked with a colon (":"). 132 o Ellipsis ("...") stands for contents of subtrees that are not 133 shown. 135 2. Design of the Data Model 137 The IS-IS YANG module is divided in two main "isis" containers that 138 are augmenting the "control-plane-protocol" lists in ietf-routing 139 module with specific IS-IS parameters. 141 One container contains the writable parameters, while the other 142 contains the operational states. 144 The figure below describes the overall structure of the isis YANG 145 module: 147 module: ietf-isis 148 augment /rt:routing-state/rt:ribs/rt:rib/rt:routes/rt:route: 149 +--ro metric?

IS-IS Configuration 438 The IS-IS configuration container is divided in: 440 o Global parameters. 442 o Per interface configuration (see Section 2.4). 444 It would to up to extension modules to augment this model to support 445 any additional parameter. 447 The model implements features, so some of the configuration statement 448 becomes optional. As an example, the ability to control the 449 administrative state of a particular IS-IS instance is optional. By 450 advertising the feature "admin-control", a device advises the client 451 that it supports the ability to shutdown a particular IS-IS instance. 453 The global configuration contains usual IS-IS parameters such as lsp- 454 mtu, lsp-lifetime, lsp-refresh, default-metric ... Within the global 455 configuration, a client can also activate one or more address- 456 families (IPv4, IPv6) through the "afs" container. 458 2.2. Multitopology Parameters 460 The model supports multitopology (MT) IS-IS as defined in [RFC5120]. 462 The "multi-topology" container is used to enable support of MT 463 extensions. 465 The "name" used in the topology list should refer to an existing RIB 466 of the device. 468 Some specific parameters could be defined for a specific topology at 469 global level and also at interface level: for example, interface 470 metric can be defined per topology. 472 2.3. Per-Level Parameters 474 Some parameters support per level configuration. In this case, the 475 parameter is built as a container with three configuration locations: 477 o top level container: corresponds to level-1-2, so the 478 configuration applies to both levels. 480 o level-1 container: corresponds to level-1 specific parameters. 482 o level-2 container: corresponds to level-2 specific parameters. 484 +--rw priority 485 | +--rw value? uint8 486 | +--rw level-1 487 | | +--rw value? uint8 488 | +--rw level-2 489 | +--rw value? uint8 491 Example : 493 494 250 495 496 100 497 498 499 200 500 501 503 An implementation SHOULD prefer a level specific parameter over 504 level-all parameter. As example, if priority is 100 for level-1, 200 505 for level-2 and 250 for top level configuration, the implementation 506 should use 100 for level-1 and 200 for level-2. 508 Some parameters like overload bit and route preference are not 509 modeled for per level configuration. If an implementation supports 510 per level configuration for such parameter, the implementation SHOULD 511 augment the current model by adding level-1 and level-2 containers 512 and SHOULD reuse existing configuration groupings. 514 Example of augmentation : 516 augment "/rt:routing/" + 517 "rt:control-plane-protocols/rt:control-plane-protocol"+ 518 "/isis:isis/isis:overload" { 519 when "rt:type = 'isis:isis'" { 520 description 521 "This augment IS-IS routing protocol when used"; 522 } 523 description 524 "This augments IS-IS overload configuration 525 with per level configuration."; 527 container level-1 { 528 uses isis:overload-global-cfg; 529 description 530 "Level 1 configuration."; 531 } 532 container level-2 { 533 uses isis:overload-global-cfg; 534 description 535 "Level 2 configuration."; 536 } 538 } 540 Moreover, if an implementation does not support per level 541 configuration for a parameter, like priority, which has per level 542 configuration, the implementation SHOULD advertise a deviation to 543 announce the non support of the level-1 and level-2 containers. 545 Finally, if an implementation supports per level configuration but 546 does not support the level-1-2 configuration, it SHOULD also 547 advertise a deviation. 549 2.4. Per-Interface Parameters 551 The per-interface section of the IS-IS instance describes the 552 interface specific parameters. 554 The interface is a reference to an interface in the Interface YANG 555 model. 557 Each interface has interface-specific parameters that may have a 558 different value per level as described in previous section. An 559 interface-specific parameter always override an IS-IS global 560 parameter . 562 Some parameters like hello-padding are defined as containers to allow 563 easy extension by vendor specific modules. 565 +--rw interfaces 566 +--rw interface* [name] 567 +--rw name if:interface-ref 568 +--rw level-type? level 569 +--rw lsp-pacing-interval? uint16 570 +--rw lsp-retransmit-interval? uint16 571 +--rw passive? boolean 572 +--rw csnp-interval? uint16 573 +--rw hello-padding 574 | +--rw enable? boolean 575 +--rw mesh-group-enable? mesh-group-state 576 +--rw mesh-group? uint8 577 +--rw interface-type? interface-type 578 +--rw enable? boolean {admin-control}? 579 +--rw tag* uint32 {prefix-tag}? 580 +--rw tag64* uint64 {prefix-tag64}? 581 +--rw node-flag? boolean {node-flag}? 582 +--rw hello-authentication 583 | +--rw (authentication-type)? 584 | | +--:(key-chain) {key-chain}? 585 | | | +--rw key-chain? key-chain:key-chain-ref 586 | | +--:(password) 587 | | +--rw key? string 588 | | +--rw (algorithm)? 589 | | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 590 | | | +--rw hmac-sha1-12? empty 591 | | +--:(md5) 592 | | | +--rw md5? empty 593 | | +--:(sha-1) 594 | | | +--rw sha-1? empty 595 | | +--:(hmac-sha-1) 596 | | | +--rw hmac-sha-1? empty 597 | | +--:(hmac-sha-256) 598 | | | +--rw hmac-sha-256? empty 599 | | +--:(hmac-sha-384) 600 | | | +--rw hmac-sha-384? empty 601 | | +--:(hmac-sha-512) 602 | | +--rw hmac-sha-512? empty 603 | +--rw level-1 604 | | +--rw (authentication-type)? 605 | | +--:(key-chain) {key-chain}? 606 | | | +--rw key-chain? key-chain:key-chain-ref 607 | | +--:(password) 608 | | +--rw key? string 609 | | +--rw (algorithm)? 610 | | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 611 | | | +--rw hmac-sha1-12? empty 612 | | +--:(md5) 613 | | | +--rw md5? empty 614 | | +--:(sha-1) 615 | | | +--rw sha-1? empty 616 | | +--:(hmac-sha-1) 617 | | | +--rw hmac-sha-1? empty 618 | | +--:(hmac-sha-256) 619 | | | +--rw hmac-sha-256? empty 620 | | +--:(hmac-sha-384) 621 | | | +--rw hmac-sha-384? empty 622 | | +--:(hmac-sha-512) 623 | | +--rw hmac-sha-512? empty 624 | +--rw level-2 625 | +--rw (authentication-type)? 626 | +--:(key-chain) {key-chain}? 627 | | +--rw key-chain? key-chain:key-chain-ref 628 | +--:(password) 629 | +--rw key? string 630 | +--rw (algorithm)? 631 | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 632 | | +--rw hmac-sha1-12? empty 633 | +--:(md5) 634 | | +--rw md5? empty 635 | +--:(sha-1) 636 | | +--rw sha-1? empty 637 | +--:(hmac-sha-1) 638 | | +--rw hmac-sha-1? empty 639 | +--:(hmac-sha-256) 640 | | +--rw hmac-sha-256? empty 641 | +--:(hmac-sha-384) 642 | | +--rw hmac-sha-384? empty 643 | +--:(hmac-sha-512) 644 | +--rw hmac-sha-512? empty 645 +--rw hello-interval 646 | +--rw value? uint16 647 | +--rw level-1 648 | | +--rw value? uint16 649 | +--rw level-2 650 | +--rw value? uint16 651 +--rw hello-multiplier 652 | +--rw value? uint16 653 | +--rw level-1 654 | | +--rw value? uint16 655 | +--rw level-2 656 | +--rw value? uint16 657 +--rw priority 658 | +--rw value? uint8 659 | +--rw level-1 660 | | +--rw value? uint8 661 | +--rw level-2 662 | +--rw value? uint8 663 +--rw metric 664 | +--rw value? wide-metric 665 | +--rw level-1 666 | | +--rw value? wide-metric 667 | +--rw level-2 668 | +--rw value? wide-metric 669 +--rw bfd {bfd}? 670 | +--rw enabled? boolean 671 +--rw afs 672 | +--rw af* [af] 673 | +--rw af identityref 674 +--rw mpls 675 | +--rw igp-ldp-sync {igp-ldp-sync}? 676 | +--rw enable? boolean 677 +--rw fast-reroute {fast-reroute}? 678 | +--rw lfa {lfa}? 679 | +--rw candidate-disabled? boolean 680 | +--rw enable? boolean 681 | +--rw remote-lfa {remote-lfa}? 682 | | +--rw enable? boolean 683 | +--rw level-1 684 | | +--rw candidate-disabled? boolean 685 | | +--rw enable? boolean 686 | | +--rw remote-lfa {remote-lfa}? 687 | | +--rw enable? boolean 688 | +--rw level-2 689 | +--rw candidate-disabled? boolean 690 | +--rw enable? boolean 691 | +--rw remote-lfa {remote-lfa}? 692 | +--rw enable? boolean 693 +--rw multi-topology {multi-topology}? 694 +--rw topology* [name] 695 +--rw name leafref 696 +--rw fast-reroute {fast-reroute}? 697 | +--rw lfa {lfa}? 698 | +--rw candidate-disabled? boolean 699 | +--rw enable? boolean 700 | +--rw remote-lfa {remote-lfa}? 701 | | +--rw enable? boolean 702 | +--rw level-1 703 | | +--rw candidate-disabled? boolean 704 | | +--rw enable? boolean 705 | | +--rw remote-lfa {remote-lfa}? 706 | | +--rw enable? boolean 707 | +--rw level-2 708 | +--rw candidate-disabled? boolean 709 | +--rw enable? boolean 710 | +--rw remote-lfa {remote-lfa}? 711 | +--rw enable? boolean 712 +--rw metric 713 +--rw value? wide-metric 714 +--rw level-1 715 | +--rw value? wide-metric 716 +--rw level-2 717 +--rw value? wide-metric 719 2.5. Authentication Parameters 721 The module enables authentication configuration through the IETF key- 722 chain module ([I-D.ietf-rtgwg-yang-key-chain]). The IS-IS module 723 imports the "ietf-key-chain" module and reuses some groupings to 724 allow global and per interface authentication configuration. If 725 global authentication is configured, an implementation SHOULD 726 authenticate PSNP, CSNP and LSPs with the authentication parameters 727 supplied. On a per interface basis, the authentication of hello PDUs 728 can be activated. 730 2.6. IGP/LDP synchronization 732 [RFC5443] defines a mechanism where IGP needs to be synchronized with 733 LDP. An "igp-ldp-sync" feature has been defined in the model to 734 support this mechanism. The "mpls/igp-ldp-sync" container under 735 "interface" allows activation of the mechanism on a per interface 736 basis. The "mpls/igp-ldp-sync" container in the global configuration 737 is empty on purpose and is not required for the activation. The goal 738 of this empty container is to allow easy augmentation with additional 739 parameters like timers for example. 741 2.7. ISO parameters 743 As IS-IS protocol is based on ISO protocol suite, some ISO parameters 744 may be required. 746 This module augments interface configuration model to support ISO 747 configuration parameters. 749 The clns-mtu can be defined under the interface. 751 2.8. IP FRR 753 This YANG model supports LFA ([RFC5286]) and remote LFA ([RFC7490]) 754 as IP FRR techniques. The "fast-reroute" container may be augmented 755 by other models to support other IPFRR flavors (MRT, TILFA ...). 757 The current version of the model supports activation of LFA and 758 remote LFA at interface only. The global "lfa" container is present 759 but kept empty to allow augmentation with vendor specific properties 760 like policies. 762 Remote LFA is considered as a child of LFA. Remote LFA cannot be 763 enabled if LFA is not enabled. 765 The "candidate-disabled" allows to mark an interface to not be used 766 as a backup. 768 2.9. Operational State 770 A "isis" container provides operational states for IS-IS. This 771 container is divided in multiple components: 773 o system-counters : provides statistical informations about the 774 global system. 776 o interface : provides configuration state information for each 777 interface. 779 o adjacencies: provides state information about current IS-IS 780 adjacencies. 782 o spf-log: provides information about SPF events on the node. 784 o lsp-log: provides information about LSP events on the node 785 (reception of an LSP or modification of local LSP). 787 o database: provides details on current LSDB. 789 o hostnames: provides information about system-id to hostname 790 mappings. 792 o fast-reroute: provides information about IP FRR. 794 3. RPC Operations 796 The "ietf-isis" module defines two RPC operations: 798 o clear-isis-database: reset the content of a particular IS-IS 799 database and restart database synchronization with the neighbors. 801 o clear-isis-adjacency: restart a particular set of IS-IS 802 adjacencies. 804 rpcs: 805 +---x clear-adjacency 806 | +--ro input 807 | +--ro routing-protocol-instance-name instance-state-ref 808 | +--ro level? level 809 | +--ro interface? string 810 +---x clear-database 811 +--ro input 812 +--ro routing-protocol-instance-name instance-state-ref 813 +--ro level? level 815 4. Notifications 817 The "ietf-isis" module introduces some notifications : 819 database-overload : raised when overload condition is changed. 821 lsp-too-large : raised when the system tries to propagate a too 822 large PDU. 824 corrupted-lsp-detected : raised when the system find that an LSP 825 that was stored in memory has become corrupted. 827 attempt-to-exceed-max-sequence : This notification is sent when 828 the system wraps the 32-bit sequence counter of an LSP. 830 id-len-mismatch : This notification is sent when we receive a PDU 831 with a different value for the System ID length. 833 max-area-addresses-mismatch : This notification is sent when we 834 receive a PDU with a different value for the Maximum Area 835 Addresses. 837 own-lsp-purge : This notification is sent when the system receives 838 a PDU with its own system ID and zero age. 840 sequence-number-skipped : This notification is sent when the 841 system receives a PDU with its own system ID and different 842 contents. The system has to reissue the LSP with a higher 843 sequence number. 845 authentication-type-failure : This notification is sent when the 846 system receives a PDU with the wrong authentication type field. 848 authentication-failure : This notification is sent when the system 849 receives a PDU with the wrong authentication information. 851 version-skew : This notification is sent when the system receives 852 a PDU with a different protocol version number. 854 area-mismatch : This notification is sent when the system receives 855 a Hello PDU from an IS that does not share any area address. 857 rejected-adjacency : This notification is sent when the system 858 receives a Hello PDU from an IS but does not establish an 859 adjacency for some reason. 861 protocols-supported-mismatch : This notification is sent when the 862 system receives a non pseudonode LSP that has no matching protocol 863 supported. 865 lsp-error-detected : This notification is sent when the system 866 receives a LSP with a parse error. 868 adjacency-change : This notification is sent when an IS-IS 869 adjacency moves to Up state or to Down state. 871 lsp-received : This notification is sent when a LSP is received. 873 lsp-generation : This notification is sent when a LSP is 874 regenerated. 876 notifications: 877 +---n database-overload 878 | +--ro instance-name?

Segment Routing 1012 The IS-IS SR YANG module is augmenting IS-IS module for both 1013 configuration and operational states. 1015 The IS-IS SR YANG module requires the base segment routing module 1016 ([I-D.ietf-spring-sr-yang]) to be supported as there is a strong 1017 relationship between those modules. 1019 The figure below describe the overall structure of the isis-sr YANG 1020 module: 1022 module: ietf-isis-sr 1023 augment /rt:routing/rt:control-plane-protocols/rt:control-plane-protocol 1024 /isis:isis: 1025 +--rw segment-routing 1026 | +--rw enabled?

Segment Routing activation 1154 Activation of segment-routing IS-IS is done by setting the "enable" 1155 leaf to true. This triggers advertisement of segment-routing 1156 extensions based on the configuration parameters that have been setup 1157 using the base segment routing module. 1159 5.2. Advertising mapping server policy 1161 The base segment routing module defines mapping server policies. By 1162 default, IS-IS will not advertise nor receive any mapping server 1163 entry. The IS-IS segment-routing module allows to advertise one or 1164 multiple mapping server policies through the "bindings/advertise/ 1165 policies" leaf-list. The "bindings/receive" leaf allows to enable 1166 the reception of mapping server entries. 1168 5.3. IP Fast reroute 1170 IS-IS SR model augments the fast-reroute container under interface. 1171 It brings the ability to activate TI-LFA (topology independent LFA) 1172 and also enhances remote LFA to use segment-routing tunneling instead 1173 of LDP. 1175 6. Interaction with Other YANG Modules 1177 The "isis" configuration container augments the "/rt:routing/ 1178 rt:control-plane-protocols/control-plane-protocol" container of the 1179 ietf-routing [I-D.ietf-netmod-routing-cfg] module by defining IS-IS 1180 specific parameters. 1182 The "isis" module augments "/if:interfaces/if:interface" with ISO 1183 specific parameters. 1185 The "isis" operational state container augments the "/rt:routing- 1186 state/rt:control-plane-protocols/control-plane-protocol" container of 1187 the ietf-routing module by defining IS-IS specific operational 1188 states. 1190 Some IS-IS specific routes attributes are added to route objects of 1191 the ietf-routing module by augmenting "/rt:routing- 1192 state/rt:ribs/rt:rib/rt:routes/rt:route". 1194 The modules defined in this document use some groupings from ietf- 1195 keychain [I-D.ietf-rtgwg-yang-key-chain] and ietf-segment routing 1196 [I-D.ietf-spring-sr-yang]. 1198 7.

Security Considerations 5406 Configuration and state data defined in this document are designed to 5407 be accessed via the NETCONF protocol [RFC6241]. 5409 As IS-IS is an IGP protocol (critical piece of the network), ensuring 5410 stability and security of the protocol is mandatory for the network 5411 service. 5413 Authors recommends to implement NETCONF access control model 5414 ([RFC6536]) to restrict access to all or part of the configuration to 5415 specific users. Access control to RPCs is also critical as RPC 5416 allows to clear protocol datastructures that would definitively 5417 impact the network service. This kind of RPC needs only to be used 5418 in specific cases by well-known experienced users. 5420 Authors consider that all the configuration is considered as 5421 sensitive/vulnerable as well as RPCs. But security teams can decide 5422 to open some part of the configuration to less experienced users 5423 depending on the internal organization, for example: 5425 o User FullWrite: would access to the whole data model. This kind 5426 of profile may be restricted to few experienced people. 5428 o User PartialWrite: would only access to configuration part within 5429 /isis/interfaces/interface. So this kind of profile is restricted 5430 to creation/modification/deletion of interfaces. This profile 5431 does not have access to RPC. 5433 o User Read: would only access to state part /isis-state. 5435 Unauthorized access to configuration or RPC may cause high damages to 5436 the network service. 5438 The /isis-state/database may contain authentication information. As 5439 presented in the description of the /isis-state/database/level- 5440 1/lsp/authentication/authentication-key, the authentication MUST 5441 never be presented in plaintext format for security reason. Authors 5442 recommend the usage of MD5 to display or return the authentication- 5443 key. 5445 Some authentication-key may also be present in the /isis 5446 configuration. When configuring IS-IS using the NETCONF protocol, 5447 authors recommends the usage of secure transport of NETCONF using SSH 5448 ([RFC6242]). 5450 10.
