Hi

I have a cisco 4006 with the 4013 and 4232-L3 card.

I have got 3 vlans and trying to use the 4232 to route between 2 of them.

the 4232 cannot ping, but it does see packets from the network.

when I do a "debug ip packet detail" then I see the requests come in from the network .. but with "encapsulation fail"

00:22:58: IP: s=192.168.33.245 (Port-channel1.833), d=192.168.35.241 (Port-channel1.835), g=192.168.35.241, len 82, forward
00:22:58: UDP src=320, dst=320
00:22:58: IP: s=192.168.33.245 (Port-channel1.833), d=192.168.35.241 (Port-channel1.835), len 82, encapsulation failed
00:22:58: UDP src=320, dst=320no

The source and destination for these requests show up in the ARP table as incomplete. I can see the arp requests being sent out ..


I dont think there is anything unusual about my configuration but it is shown below.

I took my config guide from here


Any idea greatly received.

Thanks

Si
