[c-nsp] Large number of arp entries on 2960G

[John Elliot]

Hi Guys,
Running a management vlan(11) on a 2960S stack->2960G->7200 +  2509(for OOB) - i.e. 4 IP's
sh arp on 2960s, shows 3 entries (int vlan11)sh arp on 2509, shows 3 entries (int eth0)sh arp on 7200, shows 4 entries(on dot1q vlan 11)sh arp on 2960g, shows over 1000 entries, all with the 7200's mac address, all on interface vlan11 - all entries appear to be "random" IP's, in that they are routes(IP's) learned from upstream bgp peering sessions and also some from our internal ospf...none of these bgp sessions or ospf are running in dot1q vlan11
The only difference I can see on the 2 switches vlan interfaces is the 2960g(The one with all the strange arp entries) has "no ip route-cache".
Any suggestions as to what could be causing this?
Cheers.
