Hi Shraddha, As Les pointed out, the temporary assignment for the ISIS Router Capability sub-tlv has been made.
Gunter, Since we now have the DE for the IGP Algorithm Type For Computing Flooding Topology, and the WG approves the request. Can the code point be assigned? - IGP Algorithm registry for disttopo 125 Thanks, Yingzhen On Fri, Jun 26, 2026 at 8:08 AM Les Ginsberg (ginsberg) <[email protected]> wrote: > Shraddha – > > > > As to the IS-IS Router Capability sub-TLV, temporary assignment has been > made.
