Introduction 100 This document defines a YANG data model for IS-IS routing protocol. 102 The data model covers configuration of an IS-IS routing protocol 103 instance as well as operational states. 105 1.1. Tree diagram 107 A simplified graphical representation of the data model is presented 108 in Section 2. 110 The meaning of the symbols in these diagrams is as follows: 112 o Brackets "[" and "]" enclose list keys. 114 o Curly braces "{" and "}" contain names of optional features that 115 make the corresponding node conditional. 117 o Abbreviations before data node names: "rw" means configuration 118 (read-write), and "ro" state data (read-only). 120 o Symbols after data node names: "?" means an optional node and "*" 121 denotes a "list" or "leaf-list". 123 o Parentheses enclose choice and case nodes, and case nodes are also 124 marked with a colon (":"). 126 o Ellipsis ("...") stands for contents of subtrees that are not 127 shown. 129 2. Design of the Data Model 131 The IS-IS YANG module is divided in two main "isis" containers that 132 are augmenting the "control-plane-protocol" lists in ietf-routing 133 module with specific IS-IS parameters. 135 One container contains the writable parameters, while the other 136 contains the operational states. 138 The figure below describes the overall structure of the isis YANG 139 module: 141 module: ietf-isis 142 augment /rt:routing-state/rt:ribs/rt:rib/rt:routes/rt:route: 143 +--ro metric?

IS-IS Configuration 436 The IS-IS configuration container is divided in: 438 o Global parameters. 440 o Per interface configuration (see Section 2.4). 442 Additional modules may be created this to support any additional 443 parameters. These modules should augment the ietf-isis module. 445 The model implements features, so some of the configuration statement 446 becomes optional. As an example, the ability to control the 447 administrative state of a particular IS-IS instance is optional. By 448 advertising the feature "admin-control", a device communicates to the 449 client that it supports the ability to shutdown a particular IS-IS 450 instance. 452 The global configuration contains usual IS-IS parameters such as lsp- 453 mtu, lsp-lifetime, lsp-refresh, default-metric ... 455 2.2. Multitopology Parameters 457 The model supports multitopology (MT) IS-IS as defined in [RFC5120]. 459 The "topologies" container is used to enable support of MT 460 extensions. 462 The "name" used in the topology list should refer to an existing RIB 463 of the device. 465 Some specific parameters could be defined on a per topology basis 466 both at global level and at interface level: for example, an 467 interface metric can be defined per topology. 469 Multiple address families (like IPv4 or IPv6) can also be activated 470 within the default topology. This can be achieved using the "afs" 471 container (requiring "nlpid-control" feature to be advertised). 473 2.3. Per-Level Parameters 475 Some parameters support a per level configuration. In this case, the 476 parameter is modeled as a container with three configuration 477 locations: 479 o top level container: corresponds to level-1-2, so the 480 configuration applies to both levels. 482 o level-1 container: corresponds to level-1 specific parameters. 484 o level-2 container: corresponds to level-2 specific parameters. 486 +--rw priority 487 | +--rw value? uint8 488 | +--rw level-1 489 | | +--rw value? uint8 490 | +--rw level-2 491 | +--rw value? uint8 493 Example: 495 496 250 497 498 100 499 500 501 200 502 503 505 An implementation SHOULD prefer a level specific parameter over a 506 level-all parameter. As example, if the priority is 100 for the 507 level-1, 200 for the level-2 and 250 for the top level configuration, 508 the implementation should use 100 for the level-1 and 200 for the 509 level-2. 511 Some parameters like "overload bit" and "route preference" are not 512 modeled to support a per level configuration. If an implementation 513 supports per level configuration for such parameter, this 514 implementation SHOULD augment the current model by adding both 515 level-1 and level-2 containers and SHOULD reuse existing 516 configuration groupings. 518 Example of augmentation: 520 augment "/rt:routing/" + 521 "rt:control-plane-protocols/rt:control-plane-protocol"+ 522 "/isis:isis/isis:overload" { 523 when "rt:type = 'isis:isis'" { 524 description 525 "This augment IS-IS routing protocol when used"; 526 } 527 description 528 "This augments IS-IS overload configuration 529 with per level configuration."; 531 container level-1 { 532 uses isis:overload-global-cfg; 533 description 534 "Level 1 configuration."; 535 } 536 container level-2 { 537 uses isis:overload-global-cfg; 538 description 539 "Level 2 configuration."; 540 } 542 } 544 If an implementation does not support per level configuration for a 545 parameter modeled with per level configuration, the implementation 546 SHOULD advertise a deviation to announce the non support of the 547 level-1 and level-2 containers. 549 Finally, if an implementation supports per level configuration but 550 does not support the level-1-2 configuration, it SHOULD also 551 advertise a deviation. 553 2.4. Per-Interface Parameters 555 The per-interface section of the IS-IS instance describes the 556 interface specific parameters. 558 The interface is a reference to an interface defined in the "ietf- 559 interfaces" YANG model. 561 Each interface has some interface-specific parameters that may have a 562 different per level value as described in previous section. An 563 interface-specific parameter always override an IS-IS global 564 parameter. 566 Some parameters like hello-padding are defined as containers to allow 567 easy extension by vendor specific modules. 569 +--rw interfaces 570 +--rw interface* [name] 571 +--rw name if:interface-ref 572 +--rw level-type? level 573 +--rw lsp-pacing-interval? uint16 574 +--rw lsp-retransmit-interval? uint16 575 +--rw passive? boolean 576 +--rw csnp-interval? uint16 577 +--rw hello-padding 578 | +--rw enable? boolean 579 +--rw mesh-group-enable? mesh-group-state 580 +--rw mesh-group? uint8 581 +--rw interface-type? interface-type 582 +--rw enable? boolean {admin-control}? 583 +--rw tag* uint32 {prefix-tag}? 584 +--rw tag64* uint64 {prefix-tag64}? 585 +--rw node-flag? boolean {node-flag}? 586 +--rw hello-authentication 587 | +--rw (authentication-type)? 588 | | +--:(key-chain) {key-chain}? 589 | | | +--rw key-chain? key-chain:key-chain-ref 590 | | +--:(password) 591 | | +--rw key? string 592 | | +--rw (algorithm)? 593 | | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 594 | | | +--rw hmac-sha1-12? empty 595 | | +--:(md5) 596 | | | +--rw md5? empty 597 | | +--:(sha-1) 598 | | | +--rw sha-1? empty 599 | | +--:(hmac-sha-1) 600 | | | +--rw hmac-sha-1? empty 601 | | +--:(hmac-sha-256) 602 | | | +--rw hmac-sha-256? empty 603 | | +--:(hmac-sha-384) 604 | | | +--rw hmac-sha-384? empty 605 | | +--:(hmac-sha-512) 606 | | +--rw hmac-sha-512? empty 607 | +--rw level-1 608 | | +--rw (authentication-type)? 609 | | +--:(key-chain) {key-chain}? 610 | | | +--rw key-chain? key-chain:key-chain-ref 611 | | +--:(password) 612 | | +--rw key? string 613 | | +--rw (algorithm)? 614 | | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 615 | | | +--rw hmac-sha1-12? empty 616 | | +--:(md5) 617 | | | +--rw md5? empty 618 | | +--:(sha-1) 619 | | | +--rw sha-1? empty 620 | | +--:(hmac-sha-1) 621 | | | +--rw hmac-sha-1? empty 622 | | +--:(hmac-sha-256) 623 | | | +--rw hmac-sha-256? empty 624 | | +--:(hmac-sha-384) 625 | | | +--rw hmac-sha-384? empty 626 | | +--:(hmac-sha-512) 627 | | +--rw hmac-sha-512? empty 628 | +--rw level-2 629 | +--rw (authentication-type)? 630 | +--:(key-chain) {key-chain}? 631 | | +--rw key-chain? key-chain:key-chain-ref 632 | +--:(password) 633 | +--rw key? string 634 | +--rw (algorithm)? 635 | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 636 | | +--rw hmac-sha1-12? empty 637 | +--:(md5) 638 | | +--rw md5? empty 639 | +--:(sha-1) 640 | | +--rw sha-1? empty 641 | +--:(hmac-sha-1) 642 | | +--rw hmac-sha-1? empty 643 | +--:(hmac-sha-256) 644 | | +--rw hmac-sha-256? empty 645 | +--:(hmac-sha-384) 646 | | +--rw hmac-sha-384? empty 647 | +--:(hmac-sha-512) 648 | +--rw hmac-sha-512? empty 649 +--rw hello-interval 650 | +--rw value? uint16 651 | +--rw level-1 652 | | +--rw value? uint16 653 | +--rw level-2 654 | +--rw value? uint16 655 +--rw hello-multiplier 656 | +--rw value? uint16 657 | +--rw level-1 658 | | +--rw value? uint16 659 | +--rw level-2 660 | +--rw value? uint16 661 +--rw priority 662 | +--rw value? uint8 663 | +--rw level-1 664 | | +--rw value? uint8 665 | +--rw level-2 666 | +--rw value? uint8 667 +--rw metric 668 | +--rw value? wide-metric 669 | +--rw level-1 670 | | +--rw value? wide-metric 671 | +--rw level-2 672 | +--rw value? wide-metric 673 +--rw bfd {bfd}? 674 | +--rw enable? boolean 675 +--rw afs {nlpid-control}? 676 | +--rw af* [af] 677 | +--rw af identityref 678 +--rw mpls 679 | +--rw igp-ldp-sync {igp-ldp-sync}? 680 | +--rw enable? boolean 681 +--rw fast-reroute {fast-reroute}? 682 | +--rw lfa {lfa}? 683 | +--rw candidate-disabled? boolean 684 | +--rw enable? boolean 685 | +--rw remote-lfa {remote-lfa}? 686 | | +--rw enable? boolean 687 | +--rw level-1 688 | | +--rw candidate-disabled? boolean 689 | | +--rw enable? boolean 690 | | +--rw remote-lfa {remote-lfa}? 691 | | +--rw enable? boolean 692 | +--rw level-2 693 | +--rw candidate-disabled? boolean 694 | +--rw enable? boolean 695 | +--rw remote-lfa {remote-lfa}? 696 | +--rw enable? boolean 697 +--rw topologies {multi-topology}? 698 +--rw topology* [name] 699 +--rw name leafref 700 +--rw fast-reroute {fast-reroute}? 701 | +--rw lfa {lfa}? 702 | +--rw candidate-disabled? boolean 703 | +--rw enable? boolean 704 | +--rw remote-lfa {remote-lfa}? 705 | | +--rw enable? boolean 706 | +--rw level-1 707 | | +--rw candidate-disabled? boolean 708 | | +--rw enable? boolean 709 | | +--rw remote-lfa {remote-lfa}? 710 | | +--rw enable? boolean 711 | +--rw level-2 712 | +--rw candidate-disabled? boolean 713 | +--rw enable? boolean 714 | +--rw remote-lfa {remote-lfa}? 715 | +--rw enable? boolean 716 +--rw metric 717 +--rw value? wide-metric 718 +--rw level-1 719 | +--rw value? wide-metric 720 +--rw level-2 721 +--rw value? wide-metric 723 2.5. Authentication Parameters 725 The module enables authentication configuration through the IETF key- 726 chain module ([I-D.ietf-rtgwg-yang-key-chain]). The IS-IS module 727 imports the "ietf-key-chain" module and reuses some groupings to 728 allow global and per interface configuration of authentication. If a 729 global authentication is configured, an implementation SHOULD 730 authenticate PSNP, CSNP and LSPs with the authentication parameters 731 supplied. The authentication of hello PDUs can be activated on a per 732 interface basis. 734 2.6. IGP/LDP synchronization 736 [RFC5443] defines a mechanism where IGP needs to be synchronized with 737 LDP. An "igp-ldp-sync" feature has been defined in the model to 738 support this mechanism. The "mpls/igp-ldp-sync" container under 739 "interface" allows activation of the mechanism on a per interface 740 basis. The "mpls/igp-ldp-sync" container in the global configuration 741 is empty on purpose and is not required for the activation. The goal 742 of this empty container is to allow easy augmentation with additional 743 parameters like timers for example. 745 2.7. ISO parameters 747 As IS-IS protocol is based on ISO protocol suite, some ISO parameters 748 may be required. 750 This module augments interface configuration model to support ISO 751 configuration parameters. 753 The clns-mtu can be defined under the interface. 755 2.8. IP FRR 757 This YANG model supports LFA ([RFC5286]) and remote LFA ([RFC7490]) 758 as IP FRR techniques. The "fast-reroute" container may be augmented 759 by other models to support other IPFRR flavors (MRT, TILFA ...). 761 The current version of the model supports activation of LFA and 762 remote LFA at interface only. The global "lfa" container is present 763 but kept empty to allow augmentation with vendor specific properties 764 like policies. 766 Remote LFA is considered as a child of LFA. Remote LFA cannot be 767 enabled if LFA is not enabled. 769 The "candidate-disabled" allows to mark an interface to not be used 770 as a backup. 772 2.9. Operational State 774 A "isis" container provides operational states for IS-IS. This 775 container is divided in multiple components: 777 o system-counters : provides statistical informations about the 778 global system. 780 o interface : provides configuration state information for each 781 interface. 783 o adjacencies: provides state information about current IS-IS 784 adjacencies. 786 o spf-log: provides information about SPF events on the node. 788 o lsp-log: provides information about LSP events on the node 789 (reception of an LSP or modification of local LSP). 791 o database: provides details on current LSDB. 793 o hostnames: provides information about system-id to hostname 794 mappings. 796 o fast-reroute: provides information about IP FRR. 798 3. RPC Operations 800 The "ietf-isis" module defines two RPC operations: 802 o clear-isis-database: reset the content of a particular IS-IS 803 database and restart database synchronization with the neighbors. 805 o clear-isis-adjacency: restart a particular set of IS-IS 806 adjacencies. 808 rpcs: 809 +---x clear-adjacency 810 | +--ro input 811 | +--ro routing-protocol-instance-name instance-state-ref 812 | +--ro level? level 813 | +--ro interface? string 814 +---x clear-database 815 +--ro input 816 +--ro routing-protocol-instance-name instance-state-ref 817 +--ro level? level 819 4. Notifications 821 The "ietf-isis" module introduces some notifications : 823 database-overload : raised when overload condition is changed. 825 lsp-too-large : raised when the system tries to propagate a too 826 large PDU. 828 corrupted-lsp-detected : raised when the system find that an LSP 829 that was stored in memory has become corrupted. 831 attempt-to-exceed-max-sequence : This notification is sent when 832 the system wraps the 32-bit sequence counter of an LSP. 834 id-len-mismatch : This notification is sent when we receive a PDU 835 with a different value for the System ID length. 837 max-area-addresses-mismatch : This notification is sent when we 838 receive a PDU with a different value for the Maximum Area 839 Addresses. 841 own-lsp-purge : This notification is sent when the system receives 842 a PDU with its own system ID and zero age. 844 sequence-number-skipped : This notification is sent when the 845 system receives a PDU with its own system ID and different 846 contents. The system has to reissue the LSP with a higher 847 sequence number. 849 authentication-type-failure : This notification is sent when the 850 system receives a PDU with the wrong authentication type field. 852 authentication-failure : This notification is sent when the system 853 receives a PDU with the wrong authentication information. 855 version-skew : This notification is sent when the system receives 856 a PDU with a different protocol version number. 858 area-mismatch : This notification is sent when the system receives 859 a Hello PDU from an IS that does not share any area address. 861 rejected-adjacency : This notification is sent when the system 862 receives a Hello PDU from an IS but does not establish an 863 adjacency for some reason. 865 protocols-supported-mismatch : This notification is sent when the 866 system receives a non pseudonode LSP that has no matching protocol 867 supported. 869 lsp-error-detected : This notification is sent when the system 870 receives a LSP with a parse error. 872 adjacency-change : This notification is sent when an IS-IS 873 adjacency moves to Up state or to Down state. 875 lsp-received : This notification is sent when a LSP is received. 877 lsp-generation : This notification is sent when a LSP is 878 regenerated. 880 notifications: 881 +---n database-overload 882 | +--ro instance-name?

Interaction with Other YANG Modules 1016 The "isis" configuration container augments the "/rt:routing/ 1017 rt:control-plane-protocols/control-plane-protocol" container of the 1018 ietf-routing [I-D.ietf-netmod-routing-cfg] module by defining IS-IS 1019 specific parameters. 1021 The "isis" module augments "/if:interfaces/if:interface" with ISO 1022 specific parameters. 1024 The "isis" operational state container augments the "/rt:routing- 1025 state/rt:control-plane-protocols/control-plane-protocol" container of 1026 the ietf-routing module by defining IS-IS specific operational 1027 states. 1029 Some IS-IS specific routes attributes are added to route objects of 1030 the ietf-routing module by augmenting "/rt:routing- 1031 state/rt:ribs/rt:rib/rt:routes/rt:route". 1033 The modules defined in this document use some groupings from ietf- 1034 keychain [I-D.ietf-rtgwg-yang-key-chain]. 1036 6.

Security Considerations 4579 Configuration and state data defined in this document are designed to 4580 be accessed via the NETCONF protocol [RFC6241]. 4582 As IS-IS is an IGP protocol (critical piece of the network), ensuring 4583 stability and security of the protocol is mandatory for the network 4584 service. 4586 Authors recommends to implement NETCONF access control model 4587 ([RFC6536]) to restrict access to all or part of the configuration to 4588 specific users. Access control to RPCs is also critical as RPC 4589 allows to clear protocol datastructures that would definitively 4590 impact the network service. This kind of RPC needs only to be used 4591 in specific cases by well-known experienced users. 4593 Authors consider that all the configuration is considered as 4594 sensitive/vulnerable as well as RPCs. But security teams can decide 4595 to open some part of the configuration to less experienced users 4596 depending on the internal organization, for example: 4598 o User FullWrite: would access to the whole data model. This kind 4599 of profile may be restricted to few experienced people. 4601 o User PartialWrite: would only access to configuration part within 4602 /isis/interfaces/interface. So this kind of profile is restricted 4603 to creation/modification/deletion of interfaces. This profile 4604 does not have access to RPC. 4606 o User Read: would only access to state part /isis-state. 4608 Unauthorized access to configuration or RPC may cause high damages to 4609 the network service. 4611 The /isis-state/database may contain authentication information. As 4612 presented in the description of the /isis-state/database/level- 4613 1/lsp/authentication/authentication-key, the authentication MUST 4614 never be presented in plaintext format for security reason. Authors 4615 recommend the usage of MD5 to display or return the authentication- 4616 key. 4618 Some authentication-key may also be present in the /isis 4619 configuration. When configuring IS-IS using the NETCONF protocol, 4620 authors recommends the usage of secure transport of NETCONF using SSH 4621 ([RFC6242]). 4623 8.
