First of all I want to thank everybody who helped me on this setup(2 days long
). This lab setup is simulating SNA traffic through 2 DLSW peers.Here is the co
nfigs straight from the routers. I have also added what to test for in each rou
ter.Not sure if needed but make sure you reload r1 and r2 before you start tes
ting the lab.
thank you again,
chris hugo

You do need additional 2 routers to make it to work. I took a quick look at
chapter 15 in Cisco IOS Bridging and IBM Network Solutions, it supports
quite a few different medias, but does not support HDLC. Since I don't have
2513, and could not make it to work over FR, the only one I made it to work
is on pure ethernet:
R1-dspu pu-e0-e1--R2--e0-DLSW-e0--R3--e1--e0-dspu host-R4
I think we can use this to test SNA filtering, but I don't think I would use
it in the real lab to verify DLSW - I have my serious doubt that we will
have the right media and enough routers to set it up.
You should have no problems to make it to work with your environment.
There's no need to do bit swapping with ethernet. If you decide to use token
ring's mac as reference point, I think you need to use translational
bridging.
Please let me know if you run into problems. I'll try FR again when I have a
chance.
Chang
