Diversity Association Group

Use the following CLI syntax to configure the Diversity Association Group parameters under the PCC:

classic CLI

configure router pcep
   pcc
      pce-associations
         [no] diversity association-name
            association-id [1..65535]
            no association-id
            association-source ip-address
            no association-source
            disjointness-reference
            no disjointness-reference
            disjointness-type {loose | strict}
            no disjointness-type
            diverity-type {link | node | srlg-link | srlg-node}
            no diversity-type

MD-CLI

configure router pcep
     pcc
       pce-associations
          diversity [assoc-name] string
            association-id number
            association-source ipv4-address
            disjointness-reference {true|false}
            disjointness-type {strict | loose}
            diversity-type {none | link | node | srlg-link | srlg-node}

The Association ID for the diversity type supports the user-configured mode of operation [RFC 8800]. The ID value is interpreted as a global value independent of the IP address of the PCC or PCE node that uses it to associate LSPs.

The user can configure the following parameters for the path Diversity Association:

diversity-type – link, node, srlg-link, or srlg-node. Configuration of this parameter is mandatory. If this parameter is not configured, the system does not validate the association configuration.
disjointness-type – strict or loose. The default is loose.
disjointness-reference – used to indicate if this LSP path is the reference path for the disjoint set of paths. When set, the PCE must first compute the path of this LSP, and then apply the requested disjointness type to compute the path of all other paths in the same diversity association ID. The default is no disjointness reference.

The DISJOINTNESS-CONFIGURATION TLV is used to convey the diversity parameters requested for the set of SR-TE LSPs. The PCE uses the DISJOINTNESS-STATUS TLV to convey the status of the diversity parameters after the path computation. The same flags are set to indicate whether any of the parameters were met by the returned path.
