Introduction 85 This document defines a YANG data model for ISIS routing protocol. 87 The data model covers configuration of an ISIS routing protocol 88 instance as well as operational states. 90 1.1. Tree diagram 92 A simplified graphical representation of the data model is presented 93 in Section 2. 95 The meaning of the symbols in these diagrams is as follows: 97 o Brackets "[" and "]" enclose list keys. 99 o Curly braces "{" and "}" contain names of optional features that 100 make the corresponding node conditional. 102 o Abbreviations before data node names: "rw" means configuration 103 (read-write), and "ro" state data (read-only). 105 o Symbols after data node names: "?" means an optional node and "*" 106 denotes a "list" or "leaf-list". 108 o Parentheses enclose choice and case nodes, and case nodes are also 109 marked with a colon (":"). 111 o Ellipsis ("...") stands for contents of subtrees that are not 112 shown. 114 2. Design of the Data Model 116 The ISIS YANG module is divided in two main "isis" containers that 117 are augmenting the "routing-protocol" lists in ietf-routing module 118 with specific ISIS parameters. 120 One container contains the writable parameters, while the other 121 contains the operational states. 123 The figure below describe the overall structure of the isis YANG 124 module: 126 module: ietf-isis 127 augment /rt:routing-state/rt:ribs/rt:rib/rt:routes/rt:route: 128 +--ro metric? uint32 129 +--ro tag* uint64 130 +--ro route-type? enumeration 131 +--ro segment-id? uint32 {segment-routing}? 132 augment /rt:active-route/rt:output/rt:route: 133 +--ro metric? uint32 134 +--ro tag* uint64 135 +--ro route-type? enumeration 136 +--ro segment-id? uint32 {segment-routing}? 137 augment /if:interfaces/if:interface: 138 +--rw clns-mtu? uint16 139 augment /rt:routing/rt:routing-instance/rt:routing-protocols/rt:routing-protocol: 140 +--rw isis 141 +--rw instance* [routing-instance] 142 +--rw routing-instance rt:routing-instance-ref 143 +--rw level-type? level 144 +--rw system-id? system-id 145 +--rw maximum-area-addresses? uint8 {maximum-area-addresses}? 146 +--rw area-address* area-address 147 +--rw mpls 148 | ... 149 +--rw reference-bandwidth? uint32 {reference-bandwidth}? 150 +--rw lsp-mtu? uint16 151 +--rw lsp-lifetime? uint16 152 +--rw lsp-refresh? uint16 {lsp-refresh}? 153 +--rw graceful-restart {graceful-restart}? 154 | ... 155 +--rw node-tag {node-tag}? 156 | ... 157 +--rw fast-reroute {fast-reroute}? 158 | ... 159 +--rw segment-routing {segment-routing}? 160 | ... 161 +--rw authentication* [level] 162 | ... 163 +--rw metric-type* [level] 164 | ... 165 +--rw preference* [level] 166 | ... 167 +--rw default-metric* [level] 168 | ... 169 +--rw af* [af] {nlpid-control}? 170 | ... 171 +--rw topologies* [name] {multi-topology}? 172 | ... 173 +--rw overload* [level] 174 | ... 175 +--rw overload-max-metric* [level] {overload-max-metric}? 176 | ... 177 +--rw interfaces 178 ... 179 augment /rt:routing-state/rt:routing-instance/rt:routing-protocols/rt:routing-protocol: 180 +--ro isis 181 +--ro instance* [routing-instance] 182 +--ro routing-instance rt:routing-instance-ref 183 +--ro fast-reroute {fast-reroute}? 184 | ... 185 +--ro topologies* [name] 186 | ... 187 +--ro system-counters 188 | ... 189 +--ro interfaces 190 | ... 191 +--ro spf-log 192 | ... 194 +--ro lsp-log 195 | ... 196 +--ro database 197 | ... 198 +--ro hostnames 199 ... 201 2.1. ISIS Configuration 203 The ISIS configuration currently supports both VRF-centric and 204 protocol-centric configuration. This may be changed in future. 206 In a protocol-centric configuration, the isis configuration is 207 applied within the standard-routing-instance and the instance list 208 helps to reference the routing-instance where ISIS is activated. 210 In a VRF-centric configuration, the isis configuration is applied 211 directly within the appropriate routing-instance where ISIS is 212 activated. In this case, the instance list will contain a single 213 element. 215 The ISIS configuration container is divided in: 217 o Global parameters. 219 o Per interface configuration (see Section 2.4). 221 It would to up to extension modules to augment this model to support 222 vendor specific parameters. 224 augment /rt:routing/rt:routing-instance/rt:routing-protocols/rt:routing-protocol: 225 +--rw isis 226 +--rw instance* [routing-instance] 227 +--rw routing-instance rt:routing-instance-ref 228 +--rw level-type? level 229 +--rw system-id? system-id 230 +--rw maximum-area-addresses? uint8 {maximum-area-addresses}? 231 +--rw area-address* area-address 232 +--rw mpls 233 | +--rw ipv4-router-id? inet:ipv4-address {ipv4-router-id}? 234 | +--rw ipv6-router-id? inet:ipv6-address {ipv6-router-id}? 235 | +--rw igp-ldp-sync {igp-ldp-sync}? 236 +--rw reference-bandwidth? uint32 {reference-bandwidth}? 237 +--rw lsp-mtu? uint16 238 +--rw lsp-lifetime? uint16 239 +--rw lsp-refresh? uint16 {lsp-refresh}? 240 +--rw graceful-restart {graceful-restart}? 241 | +--rw enabled? boolean 242 +--rw node-tag {node-tag}? 243 | +--rw node-tag* [tag] 244 | +--rw tag uint32 245 +--rw fast-reroute {fast-reroute}? 246 | +--rw lfa {lfa}? 247 +--rw segment-routing {segment-routing}? 248 | +--rw enabled? boolean 249 | +--rw bindings 250 | +--rw advertise? boolean 251 | +--rw receive? boolean 252 +--rw authentication* [level] 253 | +--rw (authentication-type)? 254 | | +--:(key-chain) {key-chain}? 255 | | | +--rw key-chain? key-chain:key-chain-ref 256 | | +--:(password) 257 | | +--rw key? string 258 | | +--rw (algorithm)? 259 | | +--:(hmac-sha1-12) 260 | | | +--rw hmac-sha1-12? empty 261 | | +--:(hmac-sha1-20) 262 | | | +--rw hmac-sha1-20? empty 263 | | +--:(md5) 264 | | | +--rw md5? empty 265 | | +--:(sha-1) 266 | | | +--rw sha-1? empty 267 | | +--:(hmac-sha-1) 268 | | | +--rw hmac-sha-1? empty 269 | | +--:(hmac-sha-256) 270 | | | +--rw hmac-sha-256? empty 271 | | +--:(hmac-sha-384) 272 | | | +--rw hmac-sha-384? empty 273 | | +--:(hmac-sha-512) 274 | | +--rw hmac-sha-512? empty 275 | +--rw level level 276 +--rw metric-type* [level] 277 | +--rw value? enumeration 278 | +--rw level level 279 +--rw preference* [level] 280 | +--rw (granularity)? 281 | | +--:(detail) 282 | | | +--rw internal? uint8 283 | | | +--rw external? uint8 284 | | +--:(coarse) 285 | | +--rw default? uint8 286 | +--rw level level 287 +--rw default-metric* [level] 288 | +--rw value? wide-metric 289 | +--rw level level 290 +--rw af* [af] {nlpid-control}? 291 | +--rw af identityref 292 | +--rw enabled? boolean 293 +--rw topologies* [name] {multi-topology}? 294 | +--rw enabled? boolean 295 | +--rw name rt:rib-ref 296 | +--rw fast-reroute {fast-reroute}? 297 | | +--rw lfa {lfa}? 298 | +--rw segment-routing {segment-routing}? 299 | | +--rw enabled? boolean 300 | | +--rw bindings 301 | | +--rw advertise? boolean 302 | | +--rw receive? boolean 303 | +--rw default-metric* [level] 304 | | +--rw value? wide-metric 305 | | +--rw level level 306 | +--rw node-tag {node-tag}? 307 | +--rw node-tag* [tag] 308 | +--rw tag uint32 309 +--rw overload* [level] 310 | +--rw status? boolean 311 | +--rw timeout? uint16 312 | +--rw level level 313 +--rw overload-max-metric* [level] {overload-max-metric}? 314 | +--rw status? boolean 315 | +--rw timeout? uint16 316 | +--rw level level 317 +--rw interfaces 318 +--rw interface* [name] 319 ... 321 2.2. Multitopology Parameters 323 The "topologies" list is used to enable support of MT extensions for 324 specific address families. 326 Each topology should refer to an existing RIB. 328 Some specific parameters could be defined for a specific topology at 329 global level and also at interface level. 331 2.3. Per-Level Parameters 333 Some parameters support per level configuration. In this case, the 334 parameter is built as a list, so different values could be used for 335 each level. The "level-all" permits to apply a value to both levels. 337 +--rw priority* [level] 338 | +--rw value? uint8 339 | +--rw level level 341 Example : 343 344 100 345 level-1 346 347 348 200 349 level-2 350 352 2.4. Per-Interface Parameters 354 The per-interface section of the ISIS instance describes the 355 interface specific parameters. 357 The interface is a reference to an interface in the Interface YANG 358 model. 360 Each interface has interface-specific parameters that may have a 361 different value per level as described in previous section. An 362 interface-specific parameter always override an ISIS global parameter 363 . 365 Some parameters like BFD and hello-padding are defined as containers 366 to permit easy extension by vendor specific modules. 368 +--rw interfaces 369 +--rw interface* [name] 370 +--rw name if:interface-ref 371 +--rw level-type? level 372 +--rw lsp-pacing-interval? uint16 373 +--rw lsp-retransmit-interval? uint16 374 +--rw passive? boolean 375 +--rw csnp-interval? uint16 376 +--rw hello-padding 377 | +--rw enabled? boolean 378 +--rw mesh-group-enabled? mesh-group-state 379 +--rw mesh-group? uint8 380 +--rw interface-type? interface-type 381 +--rw enabled? boolean 382 +--rw tag* uint32 {prefix-tag}? 383 +--rw tag64* uint64 {prefix-tag64}? 384 +--rw hello-authentication* [level] 385 | +--rw (authentication-type)? 386 | | +--:(key-chain) {key-chain}? 387 | | | +--rw key-chain? key-chain:key-chain-ref 388 | | +--:(password) 389 | | +--rw key? string 390 | | +--rw (algorithm)? 391 | | ... 392 | +--rw level level 393 +--rw hello-interval* [level] 394 | +--rw value? uint16 395 | +--rw level level 396 +--rw hello-multiplier* [level] 397 | +--rw value? uint16 398 | +--rw level level 399 +--rw priority* [level] 400 | +--rw value? uint8 401 | +--rw level level 402 +--rw metric* [level] 403 | +--rw value? wide-metric 404 | +--rw level level 405 +--rw af* [af] 406 | +--rw af identityref 407 | +--rw segment-routing {segment-routing}? 408 | | +--rw prefix-sid* [value] 409 | | +--rw value-type? enumeration 410 | | +--rw value uint32 411 | | +--rw node-flag? boolean 412 | | +--rw last-hop-behavior? enumeration 413 | +--rw bfd {bfd}? 414 | +--rw enabled? boolean 415 +--rw topologies* [name] 416 | +--rw name rt:rib-ref 417 | +--rw metric* [level] 418 | | +--rw value? wide-metric 419 | | +--rw level level 420 | +--rw fast-reroute {fast-reroute}? 421 | | +--rw lfa* [level] {lfa}? 422 | | +--rw candidate-disabled? boolean 423 | | +--rw enabled? boolean 424 | | +--rw remote-lfa {remote-lfa}? 425 | | | ... 426 | | +--rw level level 427 | +--rw segment-routing {segment-routing}? 428 | +--rw authorize-bundle 429 | | +--rw enabled? boolean 430 | | +--rw weight? uint8 431 | +--rw advertise-protection? enumeration 432 +--rw fast-reroute {fast-reroute}? 433 | +--rw lfa* [level] {lfa}? 434 | +--rw candidate-disabled? boolean 435 | +--rw enabled? boolean 436 | +--rw remote-lfa {remote-lfa}? 437 | | +--rw enabled? boolean 438 | +--rw level level 439 +--rw segment-routing {segment-routing}? 440 | +--rw authorize-bundle 441 | | +--rw enabled? boolean 442 | | +--rw weight? uint8 443 | +--rw advertise-protection? enumeration 444 +--rw mpls 445 +--rw igp-ldp-sync {igp-ldp-sync}? 446 +--rw enabled? boolean 448 2.5. ISO parameters 450 Some ISO parameters may be required. 452 This module augments interface configuration model to support ISO 453 configuration parameters. 455 The clns-mtu can be defined under the interface. 457 2.6. IP FRR 459 This YANG model supports LFA and remote LFA as IP FRR techniques. 460 The "fast-reroute" container may be augmented by other models to 461 support other IPFRR flavors (MRT ...). 463 The current version of the model supports activation of LFA and 464 remote LFA at interface only. The global "lfa" container is present 465 but kept empty to permit augmentation with vendor specific properties 466 like policies. 468 Remote LFA is considered as a child of LFA. Remote LFA cannot be 469 enabled if LFA is not enabled. 471 The "candidate-disabled" permit to mark an interface to not be used 472 as a backup. 474 2.7. Segment Routing 476 This item is still under discussion and some part of the proposed 477 configuration may fit in a segment-routing specific model. 479 2.8. Operational State 481 "isis" container provides operational states for ISIS. This 482 container is divided in multiple components: 484 o system-counters : provides statistical informations about the 485 global system. 487 o interface : provides configuration state information for each 488 interface. 490 o adjacencies: provides state information about current ISIS 491 adjacencies. 493 o spf-log: provides information about SPF events on the node. 495 o lsp-log: provides information about LSP events on the node 496 (reception of an LSP or modification of local LSP). 498 o database: provides details on current LSDB. 500 o hostnames: provides information about system-id to hostname 501 mappings. 503 o fast-reroute: provides information about IP FRR. 505 o segment-routing: provides information about segment-routing. 507 augment /rt:routing-state/rt:routing-instance/rt:routing-protocols/rt:routing-protocol: 508 +--ro isis 509 +--ro instance* [routing-instance] 510 +--ro routing-instance rt:routing-instance-ref 511 +--ro fast-reroute {fast-reroute}?

RPC Operations 852 The "ietf-isis" module defines two RPC operations: 854 o clear-isis-database: reset the content of a particular ISIS 855 database and restart database synchronization with the neighbors. 857 o clear-isis-adjacency: restart a particular set of ISIS 858 adjacencies. 860 rpcs: 861 +---x clear-adjacency 862 | +--ro input 863 | +--ro routing-instance-name rt:routing-instance-state-ref 864 | +--ro routing-protocol-instance-name instance-state-ref 865 | +--ro level? level 866 | +--ro interface? string 867 +---x clear-database 868 +--ro input 869 +--ro routing-instance-name rt:routing-instance-state-ref 870 +--ro routing-protocol-instance-name instance-state-ref 871 +--ro level? level 873 4. Notifications 875 The "ietf-isis" module introduces some notifications : 877 database-overload : raised when overload condition is changed. 879 lsp-too-large : raised when the system tries to propagate a too 880 large PDU. 882 corrupted-lsp-detected : raised when the system find that an LSP 883 that was stored in memory has become corrupted. 885 attempt-to-exceed-max-sequence : This notification is sent when 886 the system wraps the 32-bit sequence counter of an LSP. 888 id-len-mismatch : This notification is sent when we receive a PDU 889 with a different value for the System ID length. 891 max-area-addresses-mismatch : This notification is sent when we 892 receive a PDU with a different value for the Maximum Area 893 Addresses. 895 own-lsp-purge : This notification is sent when the system receives 896 a PDU with its own system ID and zero age. 898 sequence-number-skipped : This notification is sent when the 899 system receives a PDU with its own system ID and different 900 contents. The system has to reissue the LSP with a higher 901 sequence number. 903 authentication-type-failure : This notification is sent when the 904 system receives a PDU with the wrong authentication type field. 906 authentication-failure : This notification is sent when the system 907 receives a PDU with the wrong authentication information. 909 version-skew : This notification is sent when the system receives 910 a PDU with a different protocol version number. 912 area-mismatch : This notification is sent when the system receives 913 a Hello PDU from an IS that does not share any area address. 915 rejected-adjacency : This notification is sent when the system 916 receives a Hello PDU from an IS but does not establish an 917 adjacency for some reason. 919 protocols-supported-mismatch : This notification is sent when the 920 system receives a non pseudonode LSP that has no matching protocol 921 supported. 923 lsp-error-detected : This notification is sent when the system 924 receives a LSP with a parse error. 926 adjacency-change : This notification is sent when an ISIS 927 adjacency moves to Up state or to Down state. 929 lsp-received : This notification is sent when a LSP is received. 931 lsp-generation : This notification is sent when a LSP is 932 regenerated. 934 notifications: 935 +---n database-overload 936 | +--ro instance-name?

Interaction with Other YANG Modules 1070 The "isis" configuration container augments the "/rt:routing/ 1071 rt:routing-instance/rt:routing-protocols/routing-protocol" container 1072 of the ietf-routing module by defining ISIS specific parameters. 1074 The "isis" module augments "/if:interfaces/if:interface" with ISO 1075 specific parameters. 1077 The "isis" operational state container augments the "/rt:routing- 1078 state/rt:routing-instance/rt:routing-protocols/routing-protocol" 1079 container of the ietf-routing module by defining ISIS specific 1080 operational states. 1082 Some ISIS specific routes attributes are added to route objects of 1083 the ietf-routing module by augmenting "/rt:routing- 1084 state/rt:ribs/rt:rib/rt:routes/rt:route" and "/rt:active- 1085 route/rt:output/rt:route". 1087 6.

Security Considerations 5260 Configuration and state data defined in this document are designed to 5261 be accessed via the NETCONF protocol [RFC6241]. 5263 As ISIS is an IGP protocol (critical piece of the network), ensuring 5264 stability and security of the protocol is mandatory for the network 5265 service. 5267 Authors recommends to implement NETCONF access control model 5268 ([RFC6536]) to restrict access to all or part of the configuration to 5269 specific users. Access control to RPCs is also critical as RPC 5270 permits to clear protocol datastructures that would definitively 5271 impact the network service. This kind of RPC needs only to be used 5272 in specific cases by well-known experienced users. 5274 Authors consider that all the configuration is considered as 5275 sensitive/vulnerable as well as RPCs. But security teams can decide 5276 to open some part of the configuration to less experienced users 5277 depending on the internal organization, for example: 5279 o User FullWrite: would access to the whole data model. This kind 5280 of profile may be restricted to few experienced people. 5282 o User PartialWrite: would only access to configuration part within 5283 /isis/interfaces/interface. So this kind of profile is restricted 5284 to creation/modification/deletion of interfaces. This profile 5285 does not have access to RPC. 5287 o User Read: would only access to state part /isis-state. 5289 Unauthorized access to configuration or RPC may cause high damages to 5290 the network service. 5292 The /isis-state/database may contain authentication information. As 5293 presented in the description of the /isis-state/database/level- 5294 1/lsp/authentication/authentication-key, the authentication MUST 5295 never be presented in plaintext format for security reason. Authors 5296 recommends the usage of MD5 to present the authentication-key. 5298 Some authentication-key may also be present in the /isis 5299 configuration. When configuring ISIS using the NETCONF protocol, 5300 authors recommends the usage of secure transport of NETCONF using SSH 5301 ([RFC6242]). 5303 8.
