[c-nsp] Loop/Unreachable problem with C6500/SUP720

[Juergen Marenda]

(proxy-) ARP on wrong Interface / vlan ?
You have random /32 more specific host-routes,
compare mac-address table and arp-cache
for the current wrong routed ip.

Or are the ip's those found as ospf router-id ?

Hope this help's,

Juergen
