Actually come to think of it, sometimes index is incorrectly programmed
with 0 MTU, so it could be still MTU failure.

Try:
sh mls cef lookup DST detail
<from above 2nd line of useful output there is A:<number> take this number>
sh mls cef adjacency entry <number> detail

There you should see 'mtu: xyz' in second line. If it is MTU: 0, you found
the problem. If not, alas, keep searching. (You could try adding and
removing uRPF from interface, to circumvent another bug)

If it is MTU failure, try 'ip mtu 1499, ip mtu 1500' or so in interface,
and it should fix itself.
