Hi James,

I have made the changes you suggested but I am still unable to ping C from
A.  The content of /proc/net/mpls* on each machine are as follows.  Any
ideas whats wrong?

On A:
=====
[root@csgradpc03 net]# more mpls_*
::::::::::::::
mpls_in
::::::::::::::
0x40005000 0/0/0 gen 20 0 1 POP PEEK
::::::::::::::
mpls_labelspace
::::::::::::::
eth0    0       14
::::::::::::::
mpls_out
::::::::::::::
0x00000005 55/4620/0 3 PUSH(gen 16) SET(eth0,10.0.0.20)
::::::::::::::
mpls_tunnel
::::::::::::::
