3562.0. "RIP to IS-IS Decoding" by tunsrv2-tunnel.imc.das.dec.com::dfaust (Dennis Faust) Wed Feb 26 1997 20:20

I have a question regarding the setupof RIP over a frame relay link. 
Currently, my customer has no IP addressing set in his frame relay cloud, so 
the RIP packets are IS-IS encapsulated. I need the packets to be ttranformed 
back into RIP packets on the Ethernet port on the far end DECNIS. Does this 
happen automatically and what are the parameters that I should be looking at 
to ensure that this is the correct setting. I will have the customer verify 
that this is happening with a sniffer.

Since you have no IP addresses set on your Frame-relay circuits there is no way for RIP to work on these circuits. What you will have to do is perform route-propergation from the ISIS information recieved on yor FR circuits and propergate these into your RIP instance set on the ethernet circuit. You can then use DTF to trace the RIP packets sent out over the ethernet circuit to verify that the routes learnt via ISIS are being propergated into RIP at the correct metric.

DECNIS does not perform any kind of IP tunneling for the RIP protocol. 
Therefore no, this does not happen automatically.

Since you have no IP addresses set on your Frame-relay circuits
there is no way for RIP to work on these circuits. What you will have to do
is perform route-propergation from the ISIS information recieved on
yor FR circuits and propergate these into your RIP instance set on the 
ethernet circuit.

You can then use DTF to trace the RIP packets sent out over the 
ethernet circuit to verify that the routes learnt via ISIS
are being propergated into RIP at the correct metric.
