Hi Acee,

Are you saying this as co-chair ? If so does this indicate that LSR WG charter 
would prohibit this type of work from proceeding in this WG with the exception 
of the autodiscovery piece ?

There’s nothing in the charter that says an IGP can’t use out-of-band 
signaling. I wouldn’t break this up since the reachability detection is done in 
the IGP.

Speaking as someone who doesn’t want to waste time on needless semantics 
discussions,
Acee

Thx,
R.

[WAJ] The exact description should be “It proposes to use IGP establishing the 
out of band channel to deliver the PUB/SUB information”

Sorry - no.  You seem to be locking IGPs to flooding based transport only. 
Anything else you call "out of band" - I do not subscribe to this.

The IGP is used solely to advertise support for the registration/notification 
protocol which operates over TCP or QUIC. I’d consider this out-of-band 
signaling with respect to the IGP as well. I will comment on the draft at a 
later time as I have some more exigent matters to attend to.

Thanks,
Acee

Many thx,
R.
