Hi,
we are planning to add the backward compatibility section to
draft-ppsenak-ospf-lls-interface-id as suggested on the list, but we
wanted to assure that there are, in fact, implementations that use the
mechanism defined in RFC 4203 for interface ID discovery.
Section 3 of the RFC 4203 defines a "Link Local" TLV and "Link Local
Identifier" sub-TLV to be used to exchange the Link Local Identifier on
the unnumbered link. Interestingly enough there is no IANA registry for
the sub-TLVs of "Link Local" TLV, nor is there any value reserved for
the "Link Local Identifier" sub-TLV through IANA.
Considering above, I would like to poll the WG to see how many
implementations are actually supporting the Link Local Identifier
exchange using the link scope TE-LSA as specified in section 3 of the
RFC 4203.
thanks,
Peter
