+This case uses SRv6 end functions, End.M.GTP6.D and End.DT6.

+
+The configurations are same with IPv4 payload case, except D4:: is configured as "End.DT6" in VPP4. VPP4 decapsulates the SRv6 packet and lookup the table for the inner IPv6 packet and send out to the packet capture.
+
+If you want to use IPv6 payload instead of IPv4, you can run:
+
+```
+$ ./runner.py test gtp6_ipv6
