I am using ethereal to view the packets.  Basically, a ping packet comes in the egress with one MPLS header using the ICMP protocol.  Comes out of the Egress on the IP protocol however with 3 MPLS headers according to ethereal.  Had anybody seen this before?

The packets are traversing the stack right.  What your seeing via ethereal
and tcpdump is an intermediate state.  I've never been able to figure out
how to get around this.  If you look at the packet from another peer
on the subnet it will look just fine.
