"preference" in JUNOS is like administrative distance on IOS. It's probably a good idea to mention this when suggesting its use as a substitute for "weight" because it is conceptually different. Like weight, though, it is possible to make your iBGP domain produce unusual results if you fool around with preference. Unlike local-preference, these changes are not signaled to iBGP neighbors. In a network like: A---B---C If you alter preference on router B, it is possible that router A will send packets for a prefix which it thinks will exit the network at router C, but in fact, router B has made a different bestpath selection and picked its own neighbor as the egress for that prefix. This may make the network confusing to troubleshoot. If you had BGP customers who weren't stupid, it would anger them. If you have labeled-unicast it would not happen though. -- Jeff S Wheeler <j...@inconcepts.biz> Sr Network Operator / Innovative Network Concepts _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
