Hmmm Parry,
Look interesting. let me try an what happens.
But, what IP address do u want me to put on the BVI interface. Same subnet
as the R1's Token ring interface.
R.

Hi,
Just a suggestion for you to test, I think you can enable routing On R3
by using
IRB, ie make E0/S0 in the same brige group and assign BVI with IP
address.
Regards
Parry

Subject: WORKING Fine ( Source Route Transparent bridging.)
Hi Guys thanks for every ones help.
Here is the working config. Looks like I had not disabled the IP routing
on
one of the routers which was doing bridging. But it was good exercise.
Set up is as follows :
R1-----To--------R2---------So--------------R3---------E0-----------R4
R1 and R4 are used as end hosts, and R2 and R3 are actually doing the
bridging.
It is absolutely important that routing is disabled on R2 and R3 for
this
set up to work.
Assign some IP addresses to R1 and R4's Token ring and Ethernet
interfaces
so that they are in the same subnet. Once u are ready with
configurations on
R2 and R3 try to ping from R1 to R4.
Here is the working solution. ( Config's of R2 and R3 only).
hostname R2
