Introduction 90 This document defines a YANG data model for ISIS routing protocol. 92 The data model covers configuration of an ISIS routing protocol 93 instance as well as operational states. 95 1.1. Tree diagram 97 A simplified graphical representation of the data model is presented 98 in Section 2. 100 The meaning of the symbols in these diagrams is as follows: 102 o Brackets "[" and "]" enclose list keys. 104 o Curly braces "{" and "}" contain names of optional features that 105 make the corresponding node conditional. 107 o Abbreviations before data node names: "rw" means configuration 108 (read-write), and "ro" state data (read-only). 110 o Symbols after data node names: "?" means an optional node and "*" 111 denotes a "list" or "leaf-list". 113 o Parentheses enclose choice and case nodes, and case nodes are also 114 marked with a colon (":"). 116 o Ellipsis ("...") stands for contents of subtrees that are not 117 shown. 119 2. Design of the Data Model 121 The ISIS YANG module is divided in two main "isis" containers that 122 are augmenting the "routing-protocol" lists in ietf-routing module 123 with specific ISIS parameters. 125 One container contains the writable parameters, while the other 126 contains the operational states. 128 The figure below describe the overall structure of the isis YANG 129 module: 131 module: ietf-isis 132 augment /rt:routing-state/rt:ribs/rt:rib/rt:routes/rt:route: 133 +--ro metric?

ISIS Configuration 425 The ISIS configuration supports a VRF-centric configuration approach. 426 The isis configuration is applied directly within the appropriate 427 routing-instance where ISIS is activated. 429 The ISIS configuration container is divided in: 431 o Global parameters. 433 o Per interface configuration (see Section 2.4). 435 It would to up to extension modules to augment this model to support 436 vendor specific parameters. 438 2.2. Multitopology Parameters 440 The "topologies" list is used to enable support of MT extensions for 441 specific address families. 443 Each topology should refer to an existing RIB. 445 Some specific parameters could be defined for a specific topology at 446 global level and also at interface level. 448 2.3. Per-Level Parameters 450 Some parameters support per level configuration. In this case, the 451 parameter is built as a list, so different values could be used for 452 each level. The "level-all" permits to apply a value to both levels. 454 +--rw priority* [level] 455 | +--rw value? uint8 456 | +--rw level level 458 Example : 460 461 100 462 level-1 463 464 465 200 466 level-2 467 469 2.4. Per-Interface Parameters 471 The per-interface section of the ISIS instance describes the 472 interface specific parameters. 474 The interface is a reference to an interface in the Interface YANG 475 model. 477 Each interface has interface-specific parameters that may have a 478 different value per level as described in previous section. An 479 interface-specific parameter always override an ISIS global parameter 480 . 482 Some parameters like BFD and hello-padding are defined as containers 483 to permit easy extension by vendor specific modules. 485 +--rw interfaces 486 +--rw interface* [name] 487 +--rw name if:interface-ref 488 +--rw level-type? level 489 +--rw lsp-pacing-interval? uint16 490 +--rw lsp-retransmit-interval? uint16 491 +--rw passive? boolean 492 +--rw csnp-interval? uint16 493 +--rw hello-padding 494 | +--rw enable? boolean 495 +--rw mesh-group-enable? mesh-group-state 496 +--rw mesh-group? uint8 497 +--rw interface-type? interface-type 498 +--rw enable? boolean {admin-control}? 499 +--rw tag* uint32 {prefix-tag}? 500 +--rw tag64* uint64 {prefix-tag64}? 501 +--rw hello-authentication* [level] 502 | +--rw (authentication-type)? 503 | | +--:(key-chain) {key-chain}? 504 | | | +--rw key-chain? key-chain:key-chain-ref 505 | | +--:(password) 506 | | +--rw key? string 507 | | +--rw (algorithm)? 508 | | +--:(hmac-sha1-12) 509 | | | ... 510 | | +--:(hmac-sha1-20) 511 | | | ... 512 | | +--:(md5) 513 | | | ... 514 | | +--:(sha-1) 515 | | | ... 516 | | +--:(hmac-sha-1) 517 | | | ... 518 | | +--:(hmac-sha-256) 519 | | | ... 520 | | +--:(hmac-sha-384) 521 | | | ... 522 | | +--:(hmac-sha-512) 523 | | ... 524 | +--rw level level 525 +--rw hello-interval* [level] 526 | +--rw value? uint16 527 | +--rw level level 528 +--rw hello-multiplier* [level] 529 | +--rw value? uint16 530 | +--rw level level 531 +--rw priority* [level] 532 | +--rw value? uint8 533 | +--rw level level 534 +--rw metric* [level] 535 | +--rw value? wide-metric 536 | +--rw level level 537 +--rw af* [af] 538 | +--rw af identityref 539 | +--rw bfd {bfd}? 540 | +--rw enable? boolean 541 +--rw mpls 542 | +--rw igp-ldp-sync {igp-ldp-sync}? 543 | +--rw enable? boolean 544 +--rw fast-reroute {fast-reroute}? 545 | +--rw lfa* [level] {lfa}? 546 | +--rw candidate-disabled? boolean 547 | +--rw enable? boolean 548 | +--rw remote-lfa {remote-lfa}? 549 | | +--rw enable? boolean 550 | +--rw level level 551 +--rw topologies* [name] 552 +--rw name rt:rib-ref 553 +--rw fast-reroute {fast-reroute}? 554 | +--rw lfa* [level] {lfa}? 555 | +--rw candidate-disabled? boolean 556 | +--rw enable? boolean 557 | +--rw remote-lfa {remote-lfa}? 558 | | +--rw enable? boolean 559 | +--rw level level 560 +--rw metric* [level] 561 +--rw value? wide-metric 562 +--rw level level 564 2.5. ISO parameters 566 Some ISO parameters may be required. 568 This module augments interface configuration model to support ISO 569 configuration parameters. 571 The clns-mtu can be defined under the interface. 573 2.6. IP FRR 575 This YANG model supports LFA and remote LFA as IP FRR techniques. 576 The "fast-reroute" container may be augmented by other models to 577 support other IPFRR flavors (MRT ...). 579 The current version of the model supports activation of LFA and 580 remote LFA at interface only. The global "lfa" container is present 581 but kept empty to permit augmentation with vendor specific properties 582 like policies. 584 Remote LFA is considered as a child of LFA. Remote LFA cannot be 585 enabled if LFA is not enabled. 587 The "candidate-disabled" permit to mark an interface to not be used 588 as a backup. 590 2.7. Operational State 592 "isis" container provides operational states for ISIS. This 593 container is divided in multiple components: 595 o system-counters : provides statistical informations about the 596 global system. 598 o interface : provides configuration state information for each 599 interface. 601 o adjacencies: provides state information about current ISIS 602 adjacencies. 604 o spf-log: provides information about SPF events on the node. 606 o lsp-log: provides information about LSP events on the node 607 (reception of an LSP or modification of local LSP). 609 o database: provides details on current LSDB. 611 o hostnames: provides information about system-id to hostname 612 mappings. 614 o fast-reroute: provides information about IP FRR. 616 3. RPC Operations 618 The "ietf-isis" module defines two RPC operations: 620 o clear-isis-database: reset the content of a particular ISIS 621 database and restart database synchronization with the neighbors. 623 o clear-isis-adjacency: restart a particular set of ISIS 624 adjacencies. 626 rpcs: 627 +---x clear-adjacency 628 | +--ro input 629 | +--ro routing-instance-name rt:routing-instance-state-ref 630 | +--ro routing-protocol-instance-name instance-state-ref 631 | +--ro level? level 632 | +--ro interface? string 633 +---x clear-database 634 +--ro input 635 +--ro routing-instance-name rt:routing-instance-state-ref 636 +--ro routing-protocol-instance-name instance-state-ref 637 +--ro level? level 639 4. Notifications 641 The "ietf-isis" module introduces some notifications : 643 database-overload : raised when overload condition is changed. 645 lsp-too-large : raised when the system tries to propagate a too 646 large PDU. 648 corrupted-lsp-detected : raised when the system find that an LSP 649 that was stored in memory has become corrupted. 651 attempt-to-exceed-max-sequence : This notification is sent when 652 the system wraps the 32-bit sequence counter of an LSP. 654 id-len-mismatch : This notification is sent when we receive a PDU 655 with a different value for the System ID length. 657 max-area-addresses-mismatch : This notification is sent when we 658 receive a PDU with a different value for the Maximum Area 659 Addresses. 661 own-lsp-purge : This notification is sent when the system receives 662 a PDU with its own system ID and zero age. 664 sequence-number-skipped : This notification is sent when the 665 system receives a PDU with its own system ID and different 666 contents. The system has to reissue the LSP with a higher 667 sequence number. 669 authentication-type-failure : This notification is sent when the 670 system receives a PDU with the wrong authentication type field. 672 authentication-failure : This notification is sent when the system 673 receives a PDU with the wrong authentication information. 675 version-skew : This notification is sent when the system receives 676 a PDU with a different protocol version number. 678 area-mismatch : This notification is sent when the system receives 679 a Hello PDU from an IS that does not share any area address. 681 rejected-adjacency : This notification is sent when the system 682 receives a Hello PDU from an IS but does not establish an 683 adjacency for some reason. 685 protocols-supported-mismatch : This notification is sent when the 686 system receives a non pseudonode LSP that has no matching protocol 687 supported. 689 lsp-error-detected : This notification is sent when the system 690 receives a LSP with a parse error. 692 adjacency-change : This notification is sent when an ISIS 693 adjacency moves to Up state or to Down state. 695 lsp-received : This notification is sent when a LSP is received. 697 lsp-generation : This notification is sent when a LSP is 698 regenerated. 700 notifications: 701 +---n database-overload 702 | +--ro instance-name?

Segment Routing 836 The IS-IS SR YANG module is augmenting IS-IS module for both 837 configuration and operational states. 839 The IS-IS SR YANG module requires the base segment routing module 840 ([I-D.litkowski-spring-sr-yang]) to be supported as there is a strong 841 relationship between those modules. 843 The figure below describe the overall structure of the isis-sr YANG 844 module: 846 module: ietf-isis-sr 847 augment /rt:routing/rt:routing-instance/rt:routing-protocols/rt:routing-protocol/isis:isis: 848 +--rw segment-routing 849 +--rw enabled? boolean 850 +--rw bindings 851 +--rw advertise 852 | +--rw policies* string 853 +--rw receive? boolean 854 augment /rt:routing/rt:routing-instance/rt:routing-protocols/rt:routing-protocol/isis:isis/isis:interfaces/isis:interface: 855 +--rw segment-routing 856 +--rw adjacency-sid 857 +--rw advertise-adj-group-sid* [group-id] 858 | +--rw group-id uint32 859 +--rw advertise-protection? enumeration 860 augment /rt:routing/rt:routing-instance/rt:routing-protocols/rt:routing-protocol/isis:isis/isis:interfaces/isis:interface/isis:fast-reroute: 861 +--rw ti-lfa {ti-lfa}? 862 +--rw enable? boolean 863 augment /rt:routing/rt:routing-instance/rt:routing-protocols/rt:routing-protocol/isis:isis/isis:interfaces/isis:interface/isis:fast-reroute/isis:lfa/isis:remote-lfa: 864 +--rw use-segment-routing-path? boolean {remote-lfa-sr}? 865 augment /rt:routing-state/rt:routing-instance/rt:routing-protocols/rt:routing-protocol/isis:isis: 866 +--ro segment-routing 867 +--ro enabled? boolean 868 +--ro bindings 869 +--ro advertise 870 | +--ro policies* string 871 +--ro receive? boolean 872 augment /rt:routing-state/rt:routing-instance/rt:routing-protocols/rt:routing-protocol/isis:isis/isis:interfaces/isis:interface: 873 +--ro segment-routing 874 +--ro adjacency-sid 875 +--ro advertise-adj-group-sid* [group-id] 876 | +--ro group-id uint32 877 +--ro advertise-protection? enumeration 878 augment /rt:routing-state/rt:routing-instance/rt:routing-protocols/rt:routing-protocol/isis:isis/isis:interfaces/isis:interface/isis:adjacencies/isis:adjacency: 879 +--ro adjacency-sid* [value] 880 +--ro af? identityref 881 +--ro value uint32 882 +--ro weight? uint8 883 +--ro protection-requested? boolean 884 augment /rt:routing-state/rt:routing-instance/rt:routing-protocols/rt:routing-protocol/isis:isis/isis:database/isis:level-db/isis:lsp/isis:extended-is-neighbor/isis:neighbor: 885 +--ro sid-list* [value] 886 +--ro flags? bits 887 +--ro weight? uint8 888 +--ro neighbor-id? isis:system-id 889 +--ro value uint32 890 augment /rt:routing-state/rt:routing-instance/rt:routing-protocols/rt:routing-protocol/isis:isis/isis:database/isis:level-db/isis:lsp/isis:mt-is-neighbor/isis:neighbor: 891 +--ro sid-list* [value] 892 +--ro flags? bits 893 +--ro weight? uint8 894 +--ro neighbor-id? isis:system-id 895 +--ro value uint32 896 augment /rt:routing-state/rt:routing-instance/rt:routing-protocols/rt:routing-protocol/isis:isis/isis:database/isis:level-db/isis:lsp/isis:extended-ipv4-reachability/isis:prefixes: 897 +--ro sid-list* [value] 898 +--ro flags? bits 899 +--ro algorithm? uint8 900 +--ro value uint32 901 augment /rt:routing-state/rt:routing-instance/rt:routing-protocols/rt:routing-protocol/isis:isis/isis:database/isis:level-db/isis:lsp/isis:mt-extended-ipv4-reachability/isis:prefixes: 902 +--ro sid-list* [value] 903 +--ro flags? bits 904 +--ro algorithm? uint8 905 +--ro value uint32 906 augment /rt:routing-state/rt:routing-instance/rt:routing-protocols/rt:routing-protocol/isis:isis/isis:database/isis:level-db/isis:lsp/isis:ipv6-reachability/isis:prefixes: 907 +--ro sid-list* [value] 908 +--ro flags? bits 909 +--ro algorithm? uint8 910 +--ro value uint32 911 augment /rt:routing-state/rt:routing-instance/rt:routing-protocols/rt:routing-protocol/isis:isis/isis:database/isis:level-db/isis:lsp/isis:mt-ipv6-reachability/isis:prefixes: 912 +--ro sid-list* [value] 913 +--ro flags? bits 914 +--ro algorithm? uint8 915 +--ro value uint32 916 augment /rt:routing-state/rt:routing-instance/rt:routing-protocols/rt:routing-protocol/isis:isis/isis:database/isis:level-db/isis:lsp: 917 +--ro segment-routing-bindings* [fec range] 918 +--ro fec string 919 +--ro range uint16 920 +--ro flags? bits 921 +--ro weight? uint8 922 +--ro binding* 923 +--ro prefix-sid 924 | +--ro sid-list* [value] 925 | +--ro flags? bits 926 | +--ro algorithm? uint8 927 | +--ro value uint32 928 +--ro ero-metric? uint32 929 +--ro ero 930 | +--ro address-family? identityref 931 | +--ro loose? boolean 932 | +--ro address? string 933 +--ro backup-ero 934 | +--ro address-family? identityref 935 | +--ro loose? boolean 936 | +--ro address? string 937 +--ro unnumbered-interface-id-ero 938 | +--ro router-id? string 939 | +--ro interface-id? uint32 940 +--ro backup-unnumbered-interface-id-ero 941 +--ro router-id? string 942 +--ro interface-id? uint32 944 5.1. Segment Routing activation 946 Activation of segment-routing IS-IS is done by setting the "enabled" 947 leaf to true. This triggers advertisement of segment-routing 948 extensions based on the configuration parameters that have been setup 949 using the base segment routing module. 951 5.2. Advertising mapping server policy 953 The base segment routing module defines mapping server policies. By 954 default, IS-IS will not advertise nor receive any mapping server 955 entry. The IS-IS segment-routing module permits to advertise one or 956 multiple mapping server policies through the "bindings/advertise/ 957 policies" leaf-list. The "bindings/receive" leaf permits to enable 958 the reception of mapping server entries. 960 5.3. IP Fast reroute 962 IS-IS SR model augments the fast-reroute container under interface. 963 It brings the ability to activate TI-LFA (topology independent LFA) 964 and also enhances remote LFA to use segment-routing tunneling instead 965 of LDP. 967 6. Interaction with Other YANG Modules 969 The "isis" configuration container augments the "/rt:routing/ 970 rt:routing-instance/rt:routing-protocols/routing-protocol" container 971 of the ietf-routing module by defining IS-IS specific parameters. 973 The "isis" module augments "/if:interfaces/if:interface" with ISO 974 specific parameters. 976 The "isis" operational state container augments the "/rt:routing- 977 state/rt:routing-instance/rt:routing-protocols/routing-protocol" 978 container of the ietf-routing module by defining ISIS specific 979 operational states. 981 Some ISIS specific routes attributes are added to route objects of 982 the ietf-routing module by augmenting "/rt:routing- 983 state/rt:ribs/rt:rib/rt:routes/rt:route" and "/rt:active- 984 route/rt:output/rt:route". 986 7.

Security Considerations 5179 Configuration and state data defined in this document are designed to 5180 be accessed via the NETCONF protocol [RFC6241]. 5182 As ISIS is an IGP protocol (critical piece of the network), ensuring 5183 stability and security of the protocol is mandatory for the network 5184 service. 5186 Authors recommends to implement NETCONF access control model 5187 ([RFC6536]) to restrict access to all or part of the configuration to 5188 specific users. Access control to RPCs is also critical as RPC 5189 permits to clear protocol datastructures that would definitively 5190 impact the network service. This kind of RPC needs only to be used 5191 in specific cases by well-known experienced users. 5193 Authors consider that all the configuration is considered as 5194 sensitive/vulnerable as well as RPCs. But security teams can decide 5195 to open some part of the configuration to less experienced users 5196 depending on the internal organization, for example: 5198 o User FullWrite: would access to the whole data model. This kind 5199 of profile may be restricted to few experienced people. 5201 o User PartialWrite: would only access to configuration part within 5202 /isis/interfaces/interface. So this kind of profile is restricted 5203 to creation/modification/deletion of interfaces. This profile 5204 does not have access to RPC. 5206 o User Read: would only access to state part /isis-state. 5208 Unauthorized access to configuration or RPC may cause high damages to 5209 the network service. 5211 The /isis-state/database may contain authentication information. As 5212 presented in the description of the /isis-state/database/level- 5213 1/lsp/authentication/authentication-key, the authentication MUST 5214 never be presented in plaintext format for security reason. Authors 5215 recommends the usage of MD5 to present the authentication-key. 5217 Some authentication-key may also be present in the /isis 5218 configuration. When configuring ISIS using the NETCONF protocol, 5219 authors recommends the usage of secure transport of NETCONF using SSH 5220 ([RFC6242]). 5222 10.
