Introduction 91 This document defines a YANG data model for IS-IS routing protocol. 93 The data model covers configuration of an IS-IS routing protocol 94 instance as well as operational states. 96 1.1. Tree diagram 98 A simplified graphical representation of the data model is presented 99 in Section 2. 101 The meaning of the symbols in these diagrams is as follows: 103 o Brackets "[" and "]" enclose list keys. 105 o Curly braces "{" and "}" contain names of optional features that 106 make the corresponding node conditional. 108 o Abbreviations before data node names: "rw" means configuration 109 (read-write), and "ro" state data (read-only). 111 o Symbols after data node names: "?" means an optional node and "*" 112 denotes a "list" or "leaf-list". 114 o Parentheses enclose choice and case nodes, and case nodes are also 115 marked with a colon (":"). 117 o Ellipsis ("...") stands for contents of subtrees that are not 118 shown. 120 2. Design of the Data Model 122 The IS-IS YANG module is divided in two main "isis" containers that 123 are augmenting the "control-plane-protocol" lists in ietf-routing 124 module with specific IS-IS parameters. 126 One container contains the writable parameters, while the other 127 contains the operational states. 129 The figure below describe the overall structure of the isis YANG 130 module: 132 module: ietf-isis 133 augment /rt:routing-state/rt:ribs/rt:rib/rt:routes/rt:route: 134 +--ro metric?

IS-IS Configuration 425 The IS-IS configuration container is divided in: 427 o Global parameters. 429 o Per interface configuration (see Section 2.4). 431 It would to up to extension modules to augment this model to support 432 vendor specific parameters. 434 2.2. Multitopology Parameters 436 The "topologies" list is used to enable support of MT extensions for 437 specific address families. 439 Each topology should refer to an existing RIB. 441 Some specific parameters could be defined for a specific topology at 442 global level and also at interface level. 444 2.3. Per-Level Parameters 446 Some parameters support per level configuration. In this case, the 447 parameter is built as a container with three levels of configuration 448 : 450 o top level : corresponds to level-1-2, so the configuration applies 451 to both levels. 453 o level-1 : corresponds to level-1 specific parameter. 455 o level-2 : corresponds to level-2 specific parameter. 457 +--rw priority 458 | +--rw value? uint8 459 | +--rw level-1 460 | | +--rw value? uint8 461 | +--rw level-2 462 | +--rw value? uint8 464 Example : 466 467 250 468 469 100 470 471 472 200 473 474 476 An implementation SHOULD prefer a level specific parameter over 477 level-all parameter. As example, if priority is 100 for level-1, 200 478 for level-2 and 250 for top level configuration, the implementation 479 should use 100 for level-1 and 200 for level-2. 481 Some parameters like overload bit and route preference are not 482 modelled for per level configuration. If an implementation supports 483 per level configuration for such parameter, the implementation SHOULD 484 augment the current model by adding level-1 and level-2 containers 485 and reusing existing configuration groupings. 487 Example of augmentation : 489 augment "/rt:routing/" + 490 "rt:control-plane-protocols/rt:control-plane-protocol"+ 491 "/isis:isis/isis:overload" { 492 when "rt:type = 'isis:isis'" { 493 description 494 "This augment IS-IS routing protocol when used"; 495 } 496 description 497 "This augments IS-IS overload configuration 498 with per level configuration."; 500 container level-1 { 501 uses isis:overload-global-cfg; 502 description 503 "Level 1 configuration."; 504 } 505 container level-2 { 506 uses isis:overload-global-cfg; 507 description 508 "Level 2 configuration."; 509 } 511 } 513 Moreover, if an implementation does not support per level 514 configuration for a parameter, like priority, which has per level 515 configuration, the implementation SHOULD advertise a deviation to 516 announce the non support of the level-1 and level-2 containers. 518 Finally, if an implementation supports per level configuration but 519 does not support the level-1-2 configuration, it SHOULD also 520 advertise a deviation. 522 2.4. Per-Interface Parameters 524 The per-interface section of the IS-IS instance describes the 525 interface specific parameters. 527 The interface is a reference to an interface in the Interface YANG 528 model. 530 Each interface has interface-specific parameters that may have a 531 different value per level as described in previous section. An 532 interface-specific parameter always override an IS-IS global 533 parameter . 535 Some parameters like hello-padding are defined as containers to 536 permit easy extension by vendor specific modules. 538 +--rw interfaces 539 +--rw interface* [name] 540 +--rw name if:interface-ref 541 +--rw level-type? level 542 +--rw lsp-pacing-interval? uint16 543 +--rw lsp-retransmit-interval? uint16 544 +--rw passive? boolean 545 +--rw csnp-interval? uint16 546 +--rw hello-padding 547 | +--rw enable? boolean 548 +--rw mesh-group-enable? mesh-group-state 549 +--rw mesh-group? uint8 550 +--rw interface-type? interface-type 551 +--rw enable? boolean {admin-control}? 552 +--rw tag* uint32 {prefix-tag}? 553 +--rw tag64* uint64 {prefix-tag64}? 554 +--rw node-flag? boolean {node-flag}? 555 +--rw hello-authentication 556 | +--rw (authentication-type)? 557 | | +--:(key-chain) {key-chain}? 558 | | | +--rw key-chain? key-chain:key-chain-ref 559 | | +--:(password) 560 | | +--rw key? string 561 | | +--rw (algorithm)? 562 | | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 563 | | | +--rw hmac-sha1-12? empty 564 | | +--:(md5) 565 | | | +--rw md5? empty 566 | | +--:(sha-1) 567 | | | +--rw sha-1? empty 568 | | +--:(hmac-sha-1) 569 | | | +--rw hmac-sha-1? empty 570 | | +--:(hmac-sha-256) 571 | | | +--rw hmac-sha-256? empty 572 | | +--:(hmac-sha-384) 573 | | | +--rw hmac-sha-384? empty 574 | | +--:(hmac-sha-512) 575 | | +--rw hmac-sha-512? empty 576 | +--rw level-1 577 | | +--rw (authentication-type)? 578 | | +--:(key-chain) {key-chain}? 579 | | | +--rw key-chain? key-chain:key-chain-ref 580 | | +--:(password) 581 | | +--rw key? string 582 | | +--rw (algorithm)? 583 | | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 584 | | | +--rw hmac-sha1-12? empty 585 | | +--:(md5) 586 | | | +--rw md5? empty 587 | | +--:(sha-1) 588 | | | +--rw sha-1? empty 589 | | +--:(hmac-sha-1) 590 | | | +--rw hmac-sha-1? empty 591 | | +--:(hmac-sha-256) 592 | | | +--rw hmac-sha-256? empty 593 | | +--:(hmac-sha-384) 594 | | | +--rw hmac-sha-384? empty 595 | | +--:(hmac-sha-512) 596 | | +--rw hmac-sha-512? empty 597 | +--rw level-2 598 | +--rw (authentication-type)? 599 | +--:(key-chain) {key-chain}? 600 | | +--rw key-chain? key-chain:key-chain-ref 601 | +--:(password) 602 | +--rw key? string 603 | +--rw (algorithm)? 604 | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 605 | | +--rw hmac-sha1-12? empty 606 | +--:(md5) 607 | | +--rw md5? empty 608 | +--:(sha-1) 609 | | +--rw sha-1? empty 610 | +--:(hmac-sha-1) 611 | | +--rw hmac-sha-1? empty 612 | +--:(hmac-sha-256) 613 | | +--rw hmac-sha-256? empty 614 | +--:(hmac-sha-384) 615 | | +--rw hmac-sha-384? empty 616 | +--:(hmac-sha-512) 617 | +--rw hmac-sha-512? empty 618 +--rw hello-interval 619 | +--rw value? uint16 620 | +--rw level-1 621 | | +--rw value? uint16 622 | +--rw level-2 623 | +--rw value? uint16 624 +--rw hello-multiplier 625 | +--rw value? uint16 626 | +--rw level-1 627 | | +--rw value? uint16 628 | +--rw level-2 629 | +--rw value? uint16 630 +--rw priority 631 | +--rw value? uint8 632 | +--rw level-1 633 | | +--rw value? uint8 634 | +--rw level-2 635 | +--rw value? uint8 636 +--rw metric 637 | +--rw value? wide-metric 638 | +--rw level-1 639 | | +--rw value? wide-metric 640 | +--rw level-2 641 | +--rw value? wide-metric 642 +--rw bfd {bfd}? 643 | +--rw enabled? boolean 644 +--rw afs 645 | +--rw af* [af] 646 | +--rw af identityref 647 +--rw mpls 648 | +--rw igp-ldp-sync {igp-ldp-sync}? 649 | +--rw enable? boolean 650 +--rw fast-reroute {fast-reroute}? 651 | +--rw lfa {lfa}? 652 | +--rw candidate-disabled? boolean 653 | +--rw enable? boolean 654 | +--rw remote-lfa {remote-lfa}? 655 | | +--rw enable? boolean 656 | +--rw level-1 657 | | +--rw candidate-disabled? boolean 658 | | +--rw enable? boolean 659 | | +--rw remote-lfa {remote-lfa}? 660 | | +--rw enable? boolean 661 | +--rw level-2 662 | +--rw candidate-disabled? boolean 663 | +--rw enable? boolean 664 | +--rw remote-lfa {remote-lfa}? 665 | +--rw enable? boolean 666 +--rw multi-topology {multi-topology}? 667 +--rw topology* [name] 668 +--rw name leafref 669 +--rw fast-reroute {fast-reroute}? 670 | +--rw lfa {lfa}? 671 | +--rw candidate-disabled? boolean 672 | +--rw enable? boolean 673 | +--rw remote-lfa {remote-lfa}? 674 | | +--rw enable? boolean 675 | +--rw level-1 676 | | +--rw candidate-disabled? boolean 677 | | +--rw enable? boolean 678 | | +--rw remote-lfa {remote-lfa}? 679 | | +--rw enable? boolean 680 | +--rw level-2 681 | +--rw candidate-disabled? boolean 682 | +--rw enable? boolean 683 | +--rw remote-lfa {remote-lfa}? 684 | +--rw enable? boolean 685 +--rw metric 686 +--rw value? wide-metric 687 +--rw level-1 688 | +--rw value? wide-metric 689 +--rw level-2 690 +--rw value? wide-metric 692 2.5. ISO parameters 694 Some ISO parameters may be required. 696 This module augments interface configuration model to support ISO 697 configuration parameters. 699 The clns-mtu can be defined under the interface. 701 2.6. IP FRR 703 This YANG model supports LFA and remote LFA as IP FRR techniques. 704 The "fast-reroute" container may be augmented by other models to 705 support other IPFRR flavors (MRT ...). 707 The current version of the model supports activation of LFA and 708 remote LFA at interface only. The global "lfa" container is present 709 but kept empty to permit augmentation with vendor specific properties 710 like policies. 712 Remote LFA is considered as a child of LFA. Remote LFA cannot be 713 enabled if LFA is not enabled. 715 The "candidate-disabled" permit to mark an interface to not be used 716 as a backup. 718 2.7. Operational State 720 "isis" container provides operational states for IS-IS. This 721 container is divided in multiple components: 723 o system-counters : provides statistical informations about the 724 global system. 726 o interface : provides configuration state information for each 727 interface. 729 o adjacencies: provides state information about current IS-IS 730 adjacencies. 732 o spf-log: provides information about SPF events on the node. 734 o lsp-log: provides information about LSP events on the node 735 (reception of an LSP or modification of local LSP). 737 o database: provides details on current LSDB. 739 o hostnames: provides information about system-id to hostname 740 mappings. 742 o fast-reroute: provides information about IP FRR. 744 3. RPC Operations 746 The "ietf-isis" module defines two RPC operations: 748 o clear-isis-database: reset the content of a particular IS-IS 749 database and restart database synchronization with the neighbors. 751 o clear-isis-adjacency: restart a particular set of IS-IS 752 adjacencies. 754 rpcs: 755 +---x clear-adjacency 756 | +--ro input 757 | +--ro routing-protocol-instance-name instance-state-ref 758 | +--ro level? level 759 | +--ro interface? string 760 +---x clear-database 761 +--ro input 762 +--ro routing-protocol-instance-name instance-state-ref 763 +--ro level? level 765 4. Notifications 767 The "ietf-isis" module introduces some notifications : 769 database-overload : raised when overload condition is changed. 771 lsp-too-large : raised when the system tries to propagate a too 772 large PDU. 774 corrupted-lsp-detected : raised when the system find that an LSP 775 that was stored in memory has become corrupted. 777 attempt-to-exceed-max-sequence : This notification is sent when 778 the system wraps the 32-bit sequence counter of an LSP. 780 id-len-mismatch : This notification is sent when we receive a PDU 781 with a different value for the System ID length. 783 max-area-addresses-mismatch : This notification is sent when we 784 receive a PDU with a different value for the Maximum Area 785 Addresses. 787 own-lsp-purge : This notification is sent when the system receives 788 a PDU with its own system ID and zero age. 790 sequence-number-skipped : This notification is sent when the 791 system receives a PDU with its own system ID and different 792 contents. The system has to reissue the LSP with a higher 793 sequence number. 795 authentication-type-failure : This notification is sent when the 796 system receives a PDU with the wrong authentication type field. 798 authentication-failure : This notification is sent when the system 799 receives a PDU with the wrong authentication information. 801 version-skew : This notification is sent when the system receives 802 a PDU with a different protocol version number. 804 area-mismatch : This notification is sent when the system receives 805 a Hello PDU from an IS that does not share any area address. 807 rejected-adjacency : This notification is sent when the system 808 receives a Hello PDU from an IS but does not establish an 809 adjacency for some reason. 811 protocols-supported-mismatch : This notification is sent when the 812 system receives a non pseudonode LSP that has no matching protocol 813 supported. 815 lsp-error-detected : This notification is sent when the system 816 receives a LSP with a parse error. 818 adjacency-change : This notification is sent when an IS-IS 819 adjacency moves to Up state or to Down state. 821 lsp-received : This notification is sent when a LSP is received. 823 lsp-generation : This notification is sent when a LSP is 824 regenerated. 826 notifications: 827 +---n database-overload 828 | +--ro instance-name?

Segment Routing 962 The IS-IS SR YANG module is augmenting IS-IS module for both 963 configuration and operational states. 965 The IS-IS SR YANG module requires the base segment routing module 966 ([I-D.ietf-spring-sr-yang]) to be supported as there is a strong 967 relationship between those modules. 969 The figure below describe the overall structure of the isis-sr YANG 970 module: 972 module: ietf-isis-sr 973 augment /rt:routing/rt:control-plane-protocols/rt:control-plane-protocol 974 /isis:isis: 975 +--rw segment-routing 976 | +--rw enabled?

Segment Routing activation 1104 Activation of segment-routing IS-IS is done by setting the "enabled" 1105 leaf to true. This triggers advertisement of segment-routing 1106 extensions based on the configuration parameters that have been setup 1107 using the base segment routing module. 1109 5.2. Advertising mapping server policy 1111 The base segment routing module defines mapping server policies. By 1112 default, IS-IS will not advertise nor receive any mapping server 1113 entry. The IS-IS segment-routing module permits to advertise one or 1114 multiple mapping server policies through the "bindings/advertise/ 1115 policies" leaf-list. The "bindings/receive" leaf permits to enable 1116 the reception of mapping server entries. 1118 5.3. IP Fast reroute 1120 IS-IS SR model augments the fast-reroute container under interface. 1121 It brings the ability to activate TI-LFA (topology independent LFA) 1122 and also enhances remote LFA to use segment-routing tunneling instead 1123 of LDP. 1125 6. Interaction with Other YANG Modules 1127 The "isis" configuration container augments the "/rt:routing/ 1128 rt:control-plane-protocols/control-plane-protocol" container of the 1129 ietf-routing [I-D.ietf-netmod-routing-cfg] module by defining IS-IS 1130 specific parameters. 1132 The "isis" module augments "/if:interfaces/if:interface" with ISO 1133 specific parameters. 1135 The "isis" operational state container augments the "/rt:routing- 1136 state/rt:control-plane-protocols/control-plane-protocol" container of 1137 the ietf-routing module by defining IS-IS specific operational 1138 states. 1140 Some IS-IS specific routes attributes are added to route objects of 1141 the ietf-routing module by augmenting "/rt:routing- 1142 state/rt:ribs/rt:rib/rt:routes/rt:route". 1144 The modules defined in this document use some groupings from ietf- 1145 keychain [I-D.ietf-rtgwg-yang-key-chain] and ietf-segment routing 1146 [I-D.ietf-spring-sr-yang]. 1148 7.

Security Considerations 5628 Configuration and state data defined in this document are designed to 5629 be accessed via the NETCONF protocol [RFC6241]. 5631 As IS-IS is an IGP protocol (critical piece of the network), ensuring 5632 stability and security of the protocol is mandatory for the network 5633 service. 5635 Authors recommends to implement NETCONF access control model 5636 ([RFC6536]) to restrict access to all or part of the configuration to 5637 specific users. Access control to RPCs is also critical as RPC 5638 permits to clear protocol datastructures that would definitively 5639 impact the network service. This kind of RPC needs only to be used 5640 in specific cases by well-known experienced users. 5642 Authors consider that all the configuration is considered as 5643 sensitive/vulnerable as well as RPCs. But security teams can decide 5644 to open some part of the configuration to less experienced users 5645 depending on the internal organization, for example: 5647 o User FullWrite: would access to the whole data model. This kind 5648 of profile may be restricted to few experienced people. 5650 o User PartialWrite: would only access to configuration part within 5651 /isis/interfaces/interface. So this kind of profile is restricted 5652 to creation/modification/deletion of interfaces. This profile 5653 does not have access to RPC. 5655 o User Read: would only access to state part /isis-state. 5657 Unauthorized access to configuration or RPC may cause high damages to 5658 the network service. 5660 The /isis-state/database may contain authentication information. As 5661 presented in the description of the /isis-state/database/level- 5662 1/lsp/authentication/authentication-key, the authentication MUST 5663 never be presented in plaintext format for security reason. Authors 5664 recommends the usage of MD5 to present the authentication-key. 5666 Some authentication-key may also be present in the /isis 5667 configuration. When configuring IS-IS using the NETCONF protocol, 5668 authors recommends the usage of secure transport of NETCONF using SSH 5669 ([RFC6242]). 5671 10.
