Technical Summary

This draft presents extension needed for isis to advertise BIER information 
with in a bier domain and its subdomains. This information can be used to build 
a Bit Index Forwarding Table for BIER, which in order is used for forwarding 
multicast packets with in a BIER domain or subdomain. The ISIS extension BIER 
sub-tlv carries the information for BIER sub-domain that the router 
participates in. This sub-tlv includes multiple sub-sub-tlvs with label range 
and a bit string length for certain.

Working Group Summary

  The draft has been well received.   There has been discussion only recently 
brought to the mailing list about changing the length of
  the BAR field from 8 to 16 bits for future-proofing.  IF there is WG 
consensus on this, I expect an update before the IESG telechat
  and will pass the technical change through a 1 week WGLC before final 
approval.

Document Quality

   based on the IETF discussions there are implementation of this draft and/or 
strong roadmap commitment from other vendors. 

Personnel

   Hooman Bidgoli is the shepherd and Alvaro Retana is the Area Director
