Re: WGLC for BFD Multipoint documents (last round)

[Greg Mirsky <[e-mail]>]

Hi Reshad,
I think this is very good idea. Then in section 4.13.3 Transmitting BFD
Packets of BFD for Multipoint Networks should be edited. Perhaps the
following be acceptable:
OLD TEXT

   A system MUST NOT transmit any BFD Control packets if bfd.SilentTail
   is 1.

NEW TEXT

   A system MUST NOT transmit any BFD Control packets if bfd.SessionType is

   MultipointTail.

Will look into related changes in active tails if others agree with
the proposal in general.


Regards,

Greg
