Guys its a real world question. But I found it interesting and still don'
know the answer.
R3-frame-relay-R4--------(Some...other
network..-)--Ethernet------R1----Ethernet- (Customer network).
Task:
Routers R3 and R4 belong to some small ISP. router R1 belongs to the
customer network. The provider sends the Frame-relay over IP packets to the
customer. This means that the frames with frame-relay encapsulation are send
through the GRE tunnel from R4 to R1. The task is to receive them and send
in the cusomer network through ethernet. Is it possible to do this using
only one R1 router on the customer side?? (Although encapsulations are
different frame-relay and ethernet??)
Current solution which might be changed:
---Ethernet---R1---frame-relay--R2--customer network. Currently they need to
use R2 router... so they on R1 router remove the GRE header send it through
frame-relay to router R2 and than the frame encapsulated in ethernet goes to
the customer network.
Any ideas how to ahieve this using only R1 router (make the connection to
the ISP working)??
Thank you very much.
If needed below are the configs of routers R1 and R2 with sure changed ip
addresses.

Sorry if I have done any errors while changing the ip address.
Any ideas very appreciated.
Thanks.
