Hello,
The problem actually appears to be between the MPPPP Over Frame connection
between R3 and R2. I can ping directly across this connection fine but from
further downstream I cannot ping across it. And again oddly enough
traceroute works fine across this. I have also tried reloading the routers
and I still have the same issue. Has anyone else seen this problem ? I have
also enclosed my MLPPP config that I have double checked and looks correct
to me.
Thanks in advance,
Mike

Subject: IE Lab 8 Problem with Full IP Connectivity
Hello,
I am having a problem getting IP connectivity between R6 and SW2.
From R6 I can ping R3 e0/0 which connects to SW2 fine, but I cannot
Ping the SW2 side. From R3 you can ping SW2 fine, and from SW2 it has a
route back to R6. Also oddly enough it appears that traceroute is working.
If anyone can help explain to me what I am missing I would appreciate it :)
Thanks,
Mike F.
