Folks,

This issue has been around for a while and it is time that
we picked one of the proposals as the WG document.

My read of the consensus is that
draft-ishiguro-ospf-ospfv3-traffic-01.txt
should be used as the basis for TE for OSPFv3.

Anybody care to comment further on the topic? Preferrably with
points that have not been discussed on the list before.

Regards,
--rohit.

=>I have to agree with you here. I can't see the point of adding another
=>layer of multiplexing for these types in OSPFv3. In OSPFv2, the opaque
=>type was necessary since unknown types weren't handled. From an
=>applications standpoint, it is much more likely that one is going to
=>want to do something (whether it be process or view) all the LSAs
=>associated with a given type than all opaque LSAs.
=>
=>The only additional cost that I see is that when an opaque type is
=>requested from IANA for OSPFv2, an OSPFv3 LSA type function code must
=>also be requested.
