We're starting to deploy IPv6 in an access network and now we're wondering if short-lived RAs or some first-hop redundancy protocol is the best way to do things.
Using a Sup2T, we tried configuring 2048 interface with IPv6 using RA lifetime of 12 seconds and RA interval of 4 seconds. Failover times of 12 seconds are adequate for this purpose. The CPU load is negligible and the steady state packet rate doesn't seem to bother anything. It should be comparable to HSRP regarding PPS. I haven't tested failover times yet but it seems it should be okay according to: http://packetlife.net/blog/2011/apr/18/ipv6-neighbor-discovery-high-availability/ Any input on this? :-) -- Peter _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
