Jason,
My guess would be that the device that is attempting to forward the frame
has not recieved an ARP reply from the remote host. (show arp will prove
this). No ARP reply = no destination MAC address information =
encapsulation failed.

I've had some issues where I have been unable to ping a local/remote
router interface. Ordinarily this has occured with Frame and Dialer
interfaces. A debug ip packet shows encapsulation failed, which would
indicate that there is no mapping between the layer 2 and 3. Once the
mapping is in place, everything works as it should.
Okay, now does anyone know why I would see this on an Ethernet
interface? Both the local and remote interfaces are on the same VLAN
(and are the only devices on it) and everything looks okay from the
switch perspective as far as I can tell (i.e. neither port is disabled
and are showing pretty normal status operationally). Any pointers would
be appreciated.
