I wonder if any one could tell show me if i could bridge eoip and l2tp interfaces on mikrotik!

Many thx!

You can't bridge a l2tp interface because it's layer 3.

As for me bridging is easier done in Winbox.
Log onto the server with winbox
Click on bridge button
On Bridge window, add a new bridge(the red cross sign) and give it a name
Next, click on Ports tab and click on the red cross to add the interfaces that you want to bridge, one after the other.
Thats all
