Hi folks!
I have a 1721 with an ethernet wic. I want to bridge the fastethernet0 and ethernet0.
When I set up the bridge-group etc - I cant get frames to pass in either direction.
I need this to test vpn devices across transparent bridging and throttle the i/fs down - I can't use routing - is it possible?
Any help or tips would be greatly appreciated!
First, can you bridge the ethernet0 to fastethernet0 on the 1721.
Second, if so - config would be great!

Hello,
You need to configure protocol and bridge routing parameters.
Sample config:
bridge 1 protocol ieee
bridge irb
interface fastethernet 1/0
bridge-group 1
exit
int ethernet 0/0
bridge-group 1
exit
This should enable bridging between the interfaces.

Hi Rob, Nagaraja
Many thanks for your replies.
Nagaraja, I remember messing with the protocol and routing commands but maybe I didn't try exactly as you have shown or both together.
I'll try again tonight (It's my Lab router).
I was starting to think I might need to get a 2960 switch and use QOS!
Again, thanks for taking the trouble to reply.

I appreciate your help - thanks!
