FRRed traffic can follow very fancy routes eating bandwidth on the way. FRR for high loads is like sending trucks from a speedway to a narrow detour path through a village 10 miles away. Only effect is getting it jammed. The Internet users will also not notice a well-tuned IGP reroute or a head-end switchover to a pre-signaled backup LSP. What the VRF-based Internet users will definitely notice is (looks like RAS is tired of telling this story) is ICMP tunneling and consequent hard to interpret delay values. People are very suspicious to the numbers. This is almost impossible to explain, that the numbers, traceroute shows, have nothing to do with their kitty-photos-not-loading problem. _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
