I've been unable to get this working on sup720/12.2(33)SXI5. I get:

IP ARP req filtered src 155.198.60.2 0011.0a3a.a9c7, dst 155.198.60.1 
0000.0000.0000 wrong cable, interface Vlan600

...implying that something isn't working right. Config is:


interface Loopback60
  ip address 155.198.60.1 255.255.255.0
  ip local-proxy-arp
  ! next two lines apparently added by the above command:
  no ip redirects
  ip route-cache same-interface

interface Vlan600
  ip unnumbered Loopback60
  ip local-proxy-arp
  ! next two lines apparently added by the above command:
  no ip redirects
  ip route-cache same-interface


I get the same results if I use a vlan instead of a loopback. Any 
suggestions?
