UDLD is useful to use in the places where we use EoMPLS port-mode transport through the core. Each end-point does its autoneg with the closest PE so autoneg won't help us. (It's typically PFC3B EoMPLS and at least our IOS versions support no link-poisoning.) > I guess if it's ethernet link over some radio or something, where > autenego isn't end-to-end, it might plausibly be useful, but > generally? L2 transport services seem to make UDLD useful "generally". :-) -- Peter _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
