Subject: ISIS Adjacency issue with payload compression
Hi all,
I am having issue to form ISIS ajacency over FrameRelay network
with payload compression enable. As soon as I remove the payload
compression, I able to form ISIS adjacency. With payload compression, I see
both router are sending L1 IIH packet out, but never recive IIH packet from
remote end. I'm not sure why and need help in understanding it. Any help
would be greatly appreciated. Many tahnks in advance. Priscilla
Below are both routers configuration with FRF Payload Compression
R4(config)#do sh run int s0/0.54

Current configuration : 237 bytes
