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 "routing-protocol" lists in ietf-routing module 124 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 423 The IS-IS configuration container is divided in: 425 o Global parameters. 427 o Per interface configuration (see Section 2.4). 429 It would to up to extension modules to augment this model to support 430 vendor specific parameters. 432 2.2. Multitopology Parameters 434 The "topologies" list is used to enable support of MT extensions for 435 specific address families. 437 Each topology should refer to an existing RIB. 439 Some specific parameters could be defined for a specific topology at 440 global level and also at interface level. 442 2.3. Per-Level Parameters 444 Some parameters support per level configuration. In this case, the 445 parameter is built as a container with three levels of configuration 446 : 448 o top level : corresponds to level-1-2, so the configuration applies 449 to both levels. 451 o level-1 : corresponds to level-1 specific parameter. 453 o level-2 : corresponds to level-2 specific parameter. 455 +--rw priority 456 | +--rw value? uint8 457 | +--rw level-1 458 | | +--rw value? uint8 459 | +--rw level-2 460 | +--rw value? uint8 462 Example : 464 465 250 466 467 100 468 469 470 200 471 472 474 An implementation SHOULD prefer a level specific parameter over 475 level-all parameter. As example, if priority is 100 for level-1, 200 476 for level-2 and 250 for top level configuration, the implementation 477 should use 100 for level-1 and 200 for level-2. 479 Some parameters like overload bit and route preference are not 480 modelled for per level configuration. If an implementation supports 481 per level configuration for such parameter, the implementation SHOULD 482 augment the current model by adding level-1 and level-2 containers 483 and reusing existing configuration groupings. 485 Example of augmentation : 487 augment "/rt:routing/" + 488 "rt:routing-protocols/rt:routing-protocol"+ 489 "/isis:isis/isis:overload" { 490 when "rt:type = 'isis:isis'" { 491 description 492 "This augment IS-IS routing protocol when used"; 493 } 494 description 495 "This augments IS-IS overload configuration 496 with per level configuration."; 498 container level-1 { 499 uses isis:overload-global-cfg; 500 description 501 "Level 1 configuration."; 502 } 503 container level-2 { 504 uses isis:overload-global-cfg; 505 description 506 "Level 2 configuration."; 507 } 509 } 511 Moreover, if an implementation does not support per level 512 configuration for a parameter, like priority, which has per level 513 configuration, the implementation SHOULD advertise a deviation to 514 announce the non support of the level-1 and level-2 containers. 516 Finally, if an implementation supports per level configuration but 517 does not support the level-1-2 configuration, it SHOULD also 518 advertise a deviation. 520 2.4. Per-Interface Parameters 522 The per-interface section of the IS-IS instance describes the 523 interface specific parameters. 525 The interface is a reference to an interface in the Interface YANG 526 model. 528 Each interface has interface-specific parameters that may have a 529 different value per level as described in previous section. An 530 interface-specific parameter always override an IS-IS global 531 parameter . 533 Some parameters like hello-padding are defined as containers to 534 permit easy extension by vendor specific modules. 536 TODO : interfaces.tree 538 2.5. ISO parameters 540 Some ISO parameters may be required. 542 This module augments interface configuration model to support ISO 543 configuration parameters. 545 The clns-mtu can be defined under the interface. 547 2.6. IP FRR 549 This YANG model supports LFA and remote LFA as IP FRR techniques. 550 The "fast-reroute" container may be augmented by other models to 551 support other IPFRR flavors (MRT ...). 553 The current version of the model supports activation of LFA and 554 remote LFA at interface only. The global "lfa" container is present 555 but kept empty to permit augmentation with vendor specific properties 556 like policies. 558 Remote LFA is considered as a child of LFA. Remote LFA cannot be 559 enabled if LFA is not enabled. 561 The "candidate-disabled" permit to mark an interface to not be used 562 as a backup. 564 2.7. Operational State 566 "isis" container provides operational states for IS-IS. This 567 container is divided in multiple components: 569 o system-counters : provides statistical informations about the 570 global system. 572 o interface : provides configuration state information for each 573 interface. 575 o adjacencies: provides state information about current IS-IS 576 adjacencies. 578 o spf-log: provides information about SPF events on the node. 580 o lsp-log: provides information about LSP events on the node 581 (reception of an LSP or modification of local LSP). 583 o database: provides details on current LSDB. 585 o hostnames: provides information about system-id to hostname 586 mappings. 588 o fast-reroute: provides information about IP FRR. 590 3. RPC Operations 592 The "ietf-isis" module defines two RPC operations: 594 o clear-isis-database: reset the content of a particular IS-IS 595 database and restart database synchronization with the neighbors. 597 o clear-isis-adjacency: restart a particular set of IS-IS 598 adjacencies. 600 rpcs: 601 +---x clear-adjacency 602 | +--ro input 603 | +--ro routing-protocol-instance-name instance-state-ref 604 | +--ro level? level 605 | +--ro interface? string 606 +---x clear-database 607 +--ro input 608 +--ro routing-protocol-instance-name instance-state-ref 609 +--ro level? level 611 4. Notifications 613 The "ietf-isis" module introduces some notifications : 615 database-overload : raised when overload condition is changed. 617 lsp-too-large : raised when the system tries to propagate a too 618 large PDU. 620 corrupted-lsp-detected : raised when the system find that an LSP 621 that was stored in memory has become corrupted. 623 attempt-to-exceed-max-sequence : This notification is sent when 624 the system wraps the 32-bit sequence counter of an LSP. 626 id-len-mismatch : This notification is sent when we receive a PDU 627 with a different value for the System ID length. 629 max-area-addresses-mismatch : This notification is sent when we 630 receive a PDU with a different value for the Maximum Area 631 Addresses. 633 own-lsp-purge : This notification is sent when the system receives 634 a PDU with its own system ID and zero age. 636 sequence-number-skipped : This notification is sent when the 637 system receives a PDU with its own system ID and different 638 contents. The system has to reissue the LSP with a higher 639 sequence number. 641 authentication-type-failure : This notification is sent when the 642 system receives a PDU with the wrong authentication type field. 644 authentication-failure : This notification is sent when the system 645 receives a PDU with the wrong authentication information. 647 version-skew : This notification is sent when the system receives 648 a PDU with a different protocol version number. 650 area-mismatch : This notification is sent when the system receives 651 a Hello PDU from an IS that does not share any area address. 653 rejected-adjacency : This notification is sent when the system 654 receives a Hello PDU from an IS but does not establish an 655 adjacency for some reason. 657 protocols-supported-mismatch : This notification is sent when the 658 system receives a non pseudonode LSP that has no matching protocol 659 supported. 661 lsp-error-detected : This notification is sent when the system 662 receives a LSP with a parse error. 664 adjacency-change : This notification is sent when an IS-IS 665 adjacency moves to Up state or to Down state. 667 lsp-received : This notification is sent when a LSP is received. 669 lsp-generation : This notification is sent when a LSP is 670 regenerated. 672 notifications: 673 +---n database-overload 674 | +--ro instance-name?

Segment Routing 808 The IS-IS SR YANG module is augmenting IS-IS module for both 809 configuration and operational states. 811 The IS-IS SR YANG module requires the base segment routing module 812 ([I-D.ietf-spring-sr-yang]) to be supported as there is a strong 813 relationship between those modules. 815 The figure below describe the overall structure of the isis-sr YANG 816 module: 818 module: ietf-isis-sr 819 augment /rt:routing/rt:control-plane-protocols/ 820 rt:control-plane-protocol/isis:isis: 821 +--rw segment-routing 822 | +--rw enabled?

Segment Routing activation 959 Activation of segment-routing IS-IS is done by setting the "enabled" 960 leaf to true. This triggers advertisement of segment-routing 961 extensions based on the configuration parameters that have been setup 962 using the base segment routing module. 964 5.2. Advertising mapping server policy 966 The base segment routing module defines mapping server policies. By 967 default, IS-IS will not advertise nor receive any mapping server 968 entry. The IS-IS segment-routing module permits to advertise one or 969 multiple mapping server policies through the "bindings/advertise/ 970 policies" leaf-list. The "bindings/receive" leaf permits to enable 971 the reception of mapping server entries. 973 5.3. IP Fast reroute 975 IS-IS SR model augments the fast-reroute container under interface. 976 It brings the ability to activate TI-LFA (topology independent LFA) 977 and also enhances remote LFA to use segment-routing tunneling instead 978 of LDP. 980 6. Interaction with Other YANG Modules 982 The "isis" configuration container augments the "/rt:routing/ 983 rt:control-plane-protocols/control-plane-protocol" container of the 984 ietf-routing [I-D.ietf-netmod-routing-cfg] module by defining IS-IS 985 specific parameters. 987 The "isis" module augments "/if:interfaces/if:interface" with ISO 988 specific parameters. 990 The "isis" operational state container augments the "/rt:routing- 991 state/rt:control-plane-protocols/control-plane-protocol" container of 992 the ietf-routing module by defining IS-IS specific operational 993 states. 995 Some IS-IS specific routes attributes are added to route objects of 996 the ietf-routing module by augmenting "/rt:routing- 997 state/rt:ribs/rt:rib/rt:routes/rt:route". 999 The modules defined in this document use some groupings from ietf- 1000 keychain [I-D.ietf-rtgwg-yang-key-chain] and ietf-segment routing 1001 [I-D.ietf-spring-sr-yang]. 1003 7.

Security Considerations 5429 Configuration and state data defined in this document are designed to 5430 be accessed via the NETCONF protocol [RFC6241]. 5432 As IS-IS is an IGP protocol (critical piece of the network), ensuring 5433 stability and security of the protocol is mandatory for the network 5434 service. 5436 Authors recommends to implement NETCONF access control model 5437 ([RFC6536]) to restrict access to all or part of the configuration to 5438 specific users. Access control to RPCs is also critical as RPC 5439 permits to clear protocol datastructures that would definitively 5440 impact the network service. This kind of RPC needs only to be used 5441 in specific cases by well-known experienced users. 5443 Authors consider that all the configuration is considered as 5444 sensitive/vulnerable as well as RPCs. But security teams can decide 5445 to open some part of the configuration to less experienced users 5446 depending on the internal organization, for example: 5448 o User FullWrite: would access to the whole data model. This kind 5449 of profile may be restricted to few experienced people. 5451 o User PartialWrite: would only access to configuration part within 5452 /isis/interfaces/interface. So this kind of profile is restricted 5453 to creation/modification/deletion of interfaces. This profile 5454 does not have access to RPC. 5456 o User Read: would only access to state part /isis-state. 5458 Unauthorized access to configuration or RPC may cause high damages to 5459 the network service. 5461 The /isis-state/database may contain authentication information. As 5462 presented in the description of the /isis-state/database/level- 5463 1/lsp/authentication/authentication-key, the authentication MUST 5464 never be presented in plaintext format for security reason. Authors 5465 recommends the usage of MD5 to present the authentication-key. 5467 Some authentication-key may also be present in the /isis 5468 configuration. When configuring IS-IS using the NETCONF protocol, 5469 authors recommends the usage of secure transport of NETCONF using SSH 5470 ([RFC6242]). 5472 10.
