Hi guys, What could be happening to this packet...it says failed:
*Mar 1 03:04:01.199: IP: tableid=0, s=220.127.116.11 (Ethernet0/0), d=18.104.22.168 (Ethernet0/0), routed via RIB
*Mar 1 03:04:01.199: IP: s=22.214.171.124 (Ethernet0/0), d=126.96.36.199 (Ethernet0/0), g=188.8.131.52, len 100, forward
*Mar 1 03:04:01.207: IP: s=184.108.40.206 (Ethernet0/0), d=220.127.116.11 (Ethernet0/0), len 100, encapsulation failed
That error looks like an arp error...
Yep, here is a link that explains it from cisco: http://www.cisco.com/en/US/products/sw/iosswrel/ps1831/products_tech_note09186a00800a6057.shtml
Encap failure means layer 2 addressing failure;
often we see this in FR encap where DLCI cannot be assign to destination;
less often in Ethernet where MAC cannot be found.
Unless you have one helluva netmask, those aren't on the same subnet.
Got a route for it? Otherwise, yes, next-hop lookup (L3 or L2) seems to have failed you.
As Martin said, it is probably a l2 error.
I had same when I use static route to broadcast interface (for example ethernet) and I pointed the route to interface not to next hop. (newest ios warn you to add next hop ip not just interface)
Try sh ip arp for your next hop.
