Re: OSPFv3 Extension Future Direction (this ought to get your attention)

[Vishwas Manral <Vishwas at SINETT.COM>]

Hi Acee,

I have not read the draft yet. 

Having implemented both OSPF and IS-IS from scratch, my view is that the
OSPF LSA's have a big advantage of all relevant information being
clubbed togather. I think having extensible LSA's with TLV's(hybrid
approach) is the best approach (like in Pyda's draft) but I am not sure
we want to go to a fully TLV based approach.

Thanks,
Vishwas

Acee,

I had done some work previously on using new LSAs for advertising
topology and
prefix info into TE networks (draft-srisuresh-ospf-te-07.txt). This
draft can
be a good starting point to use for turning into future MT extensions to
OSPFv3. 

I have not been active on this work recently due to my work priorities.
However, if there are folks on the list interested in pursuing, I would
be
happy to work with you on the effort and discussion. 

Thanks.

cheers,
suresh
