Hello,
Anyone knows if you need to do anything special on the tunnel link for
this to work? Like run tag-switching there for example?
I have 2 cisco 2651xm acting as PE and have a GRE with IPSEC transport
mode between them. The CE has all the routes to the other CE, mBGP look
good, everything look good from the show perspective, but I just can't
source ping or ping from one sun box behind one CE to the other one.
Any help would be greatly appreciated.

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.
PEs = 2651xm running 12.3.1a enterprise 3DES.
Traceroute die at the PE.
Here are some show routes
