Re: Detecting inactive neighbors over demand circuit

[Acee Lindem <acee at REDBACK.COM>]

Hi Anu,
The draft doesn't specify that you have to use a router LSA, it simply uses
it as an example (draft-ietf-ospf-dc-07.txt). Also note
that link LSAs are not flooded over virtual links (which are demand
circuits by default). Having said that, a link LSA would seem like a good
choice for probing on a non-virtual OSPFv3 interface.

Note that this draft has been around for quite some time and is currently
in the RFC editor's queue.

Thanks,
Acee
