Hi Mikael, Exactly. For the duration of gr timer you continue to forward till your bgp session restarts and finishes sending you routes with end-of-rib marker. You also do not propagate neither new best paths nor withdraws to your other peers during this restart limiting amount of bgp churn. Then you compare "stale" routes with fresh ones and adjust the delta both within your box and to peers. Just try it out ;) //R.

But from what I'm reading here, I would have been wrong? The session would go down but RIB/FIB would be untouched because GR? -- Mikael Abrahamsson email: swmike@swm.pp.se _______________________________________________ Idr mailing list Idr@ietf.org https://www.ietf.org/mailman/listinfo/idr
