If a transit router in your AS treats-as-withdraw a prefix, other routers may try to send traffic across it, but the router which has treated-as-withdraw will either have no information for that route, or it will have made a different bestpath choice. This could cause a loop or a blackhole. [SR] If the transit router treated the prefix as "withdrawn", then it will remove the corresponding path. If there are no other paths for that net, then the router would send withdraws for that prefix to its own peers. So no other router would send traffic to it in the steady state. _______________________________________________ GROW mailing list [email protected] https://www.ietf.org/mailman/listinfo/grow
