I am trying to upgrade routers from Cisco 2800 to 4454 series, attached are both configurations.
With the Cisco ISR 2800 series we used “Bridging” to interconnect networks at each of their interfaces in the same segment using the IEEE protocol compatible with STP (Spanning Tree Protocol).
However, now the syntax with the new Cisco ISR 4454 has changed, also it seems that IEEE protocol has disappeared.
Main problem is with the E1 serial interfaces (serial interfaces), configurations and tests have been carried out directly interconnected the E1 between two ISR 4454 equipment and the PPP link is lifted correctly, however, because the way to assign a bridge-domain on the serial interfaces, I dont' have IP traffic flow.
How do I configure an E1 serial interface on ISR445 router, using BDI?
