Strange ARP behaviour/storm from IOS 12.3(11)T3
Posts: n/a
We have a border router, a 7206VXR running 12.3(11)T3 which gateways
our entire class B network into a local area network feeding 10
routers. OSPF is used internally, and the gateway router is seeing all
the appropriate next-hops.

The gateway router has decided that it needs to maintain, and regularly
for the entire class B on the interior network. They are not
ARP's, but rather, directed at the appropriate next-hop ethernet

The gateway router has been running this release for about 3 weeks. I
say for sure, but I believe this behavior just started this weekend.
If it
had started earlier, it surely would have been noticed, since it does
the monitoring of our internal wireless lan when the ARP storm hits
network every 3 minutes. There have been no significant changes to
router (except for the OS upgrade) in over a year.

Note that this is a continuous action, not sporadic due to some outside

Anyone have an idea what may be causing this, or what I can do to stop
