So apparently you've got MPLS GRE encapsulated packets, googling that doesn't bring up a quick answer. Perhaps another monk who's worked with it before knows more about it, or you could try asking on a Wireshark help forum, since you can apply any Wireshark filters with tshark. Or you may end up having to dig into the packet manually....
