Hello expert,

Now I want to use 1921 router with HWIC-4SHDSL-E card to connect these two ste together.

Hello Acbennyma,

interfaces that are member of a bridge-group cannot have an IP address, using IRB as you would like to do you can have an IP address only on the BVI1 logical interface.

The LAN interface and the ATM interface are just members of the bridge-group with no L3 configuration.

Besides this, the configuration of CO side looks like reasonable

Hope to help

Giuseppe
