The GRE Protocol Type 0x2000 is used by Cisco gear to encapsulate CDP frames. What would be the easiest way to modify the GRE dissector to interpret the Data within the GRE payload as a CDP frame when the GRE Protocol Type is 0x2000 ?

Hi, You should make the CDP dissector register in the "gre.proto" dissector table. If you raise a bug and attach a sample trace it should be easy to implement.
