Hello,
I have a set up like this: 
cisco2621A----ethernet/BGP----PE1--------GRE/IPSEC-------PE2----Ethernet
/BGP---cisco2621C
running eigrp inside the tunnel to advertise the loopback for the mbgp peers
PEs = 2651xm running 12.3.1a enterprise 3DES.
>From the CEs, routing table does have route between them - mbgp established 
and carried routes but i can't ping from sun box behind the one CE to the 
other sun box behind the other CE.  Traceroute die at the PE. Anyone knows 
what could be wrong?  do i need to run tag-switching inside the tunnel?

Thanks.

Regards,
