Hey guys,
I've got an issue with a router whereby 50% of packets addressed to the HSRP address are dropped. The routers have 2 HSRP pools one is ok, the other one (172.18.8.1) drops 50% of packets, but all physical interfaces respond 100%
both are 2621XMs running 12.2(31) with no errors in the logs, standby & arp debugs havent produced anything interesting.
any help greatly appreciated, prefer not to reboot yet.
cheers
