Query on SRGB's in the SR capability sub-TLV under isis link-state-database

Open nikhil2553 opened this issue 4 years ago • 0 comments

RFC8667 defines the For SR capability sub-TLV. (https://datatracker.ietf.org/doc/html/rfc8667#section-3.1) The sub-TLV can have multiple Segment Routing Global Block (SRGB) Descriptor entries each of which have the range and the sid/label sub-tlv.

In the OpenConfig model, it is present at path - At the /network-instances/network-instance/protocols/protocol/isis/levels/level/link-state-database/lsps/lsp/tlvs/tlv/router-capabilities/capability/subtlvs/subtlv/segment-routing-capability/srgb-descriptors/

The srbg-descriptors has a list srgb-descriptor but the key of which is range which restricts having multiple SRGB descriptors with the same range. For example -

     SR-Cap: range: 100, SID value: 100

     SR-Cap: range: 100, SID value: 1000

     SR-Cap: range: 100, SID value: 500

With the current model it's not possible to map these.
