Bruno, the PIC is used unchanged with PULSE. The only difference is that the PIC is triggered by the pulse arrival, instead of the IGP route removal. We have made a prototype of it and it works fine. thanks, Peter On 06/01/2022 09:09, bruno.decra...@orange.com wrote: Hi Gyan, You are

Hi Gyan, You are referring to both summarization and BGP PIC (edge). BGP PIC is quite old story, but if my memory serve me well, BGP PIC edge relies on the presence of the specific (/32) prefix information in the FIB. Hence it’s not clear to me how you can have both prefix summarization and BGP

Peter, So far you and others have been saying all along that one of the applications which uses PULSE can be BGP. If so I am afraid this is not PIC (== Prefix *Independent *Convergence) anymore. And I think this was Bruno's valid point. Today BGP registers with RIB next hops for tracking, When

The way I read this is that other applications could use the generic IGP pulse mechanism as opposed to other applications using the route unreachable signals conveyed using the IGP pulse mechanism. Thanks, Acee From: Lsr on behalf of Robert Raszuk Date: Thursday, January 6, 2022 at 6:54 AM

Hi Bruno As far as BGP PIC (edge) it is completely orthogonal to summarization framework the PUA/PULSE solutions is addressing. Let’s say for example you have ingress area A and egress area B and both have summaries of the other area. So all LPM longer matches for ingress area A exist within
