Re: [Isis-wg] [Bier] WGLC: draft-ietf-bier-isis-extensions-04

Terminology is a bit nits  IMO since the doc is reading clear enough for
someone who read BIER & ISIS. I can reread it or Les can comment whether we
should tighten glossary ...

With the scope I agree, that got lost and the doc should be possibly rev'ed
before closing LC. Yes, we flood AD wide was the agreement but something
mentioning that this could change in the future is good so we are forced to
give it some thought how that would transition ...

Thinking further though, in ISIS we have a clean document really. The  BIER
sub-TLVs go into well defined TLVs in terms of flooding scope. Normal L1-L2
redistribution can be used to get the info to all needed places AFAIS. So
maybe nothing needs to be written. I wait for Les to chime in.

OSPF I would have to look @ scopes again & think whether we need to write
something or maybe Peter can comment ...
