IETF and CISCO encapsulation differ each other only second word in packet.
CISCO second word refer to protocol, IETF has fixed value. Other content of
the packet same.
Therefore if you have only IP across network. Probably it will work.
PS: now i have no time and can't find FrameRelay packet format.
