Hi Authors of draft-ietf-spring-srv6-yang, Going through the draft, and in particular the YANG model here are a couple of comments.
In the srv6-base-model, under srv6/locators/locator/prefix XPath, you specify the prefix as a combination of address and length. However, address is specified as a 'type ipv6-address', and not 'type ipv6-prefix’? Unless you wanted to specify the prefix length using a separate node, which you call ‘length’ and put some constraint on it. From the description, which says “Locator (prefix) length”, that is what it appears to be. However, the ’type srv6-locator-len’, has a constraint of 32..96, I cannot seem to find a reference in a RFC that talks about that constraint. Can you point me to where this constraint is coming from? Also, is there a way to specify fields of SRv6 SID Structure Sub-Sub-TLV defined in RFC 9252, such as Locator Block Node Length or Locator Node Length somewhere in the model? Or is that out of scope of this document? Thanks. Mahesh Jethanandani mjethanand...@gmail.com
