I'm trying to configure a bridge for non-routed protocols between two VLANs (bridge is to be used by SNA), but up to now I've failed. I read a lot of docs, but still can't figure it out.
Consider the following topology:
Client --- 2950 --- 3550 --- Mainframe
The client is on VLAN 2 while Mainframe is on VLAN 1. The VLANs are on different IP segments, so we are routing between the VLANs (using the 3550). Using TCP/IP, everything works fine but SNA doesn't go through.
I planned on creating a bridge, puting VLAN 1 and VLAN 2 on the same bridge group.
In the 3550, I issued: (config)# bridge 1 protocol vlan-bridge (config)# int vlan 1 (config-if)# bridge-group 1 (config-if)# exit (config)# int vlan 2 (config-if)# bridge-group 1
Looked simple...but those commands don't exist in the 2950, and so I'm not even sure now that this config was the good one to be done.
Any hint ? There are a lot of very complex docs out there, but I just want to do a simple bridge for non-routed protocols.
