Bridging on IOS XR Trunk Interfaces: Example

This example shows how to configure a as a simple L2 switch.
Important notes:
Create a bridge domain that has four attachment circuits (AC). Each AC is an IOS XR trunk interface (i.e.
not a subinterface/EFP).
• This example assumes that the running config is empty, and that all the components are created.
• This example provides all the necessary steps to configure the to perform switching between the interfaces.
• The bridge domain is in a no shut state, immediately after being created.
• Only trunk (i.e. main) interfaces are used in this example.
• The trunk interfaces are capable of handling tagged (i.e. IEEE 802.1Q) or untagged (i.e. no VLAN header)
• The bridge domain learns, floods, and forwards based on MAC address. This functionality works for
• The bridge domain entity spans the entire system. It is not necessary to place all the bridge domain ACs
• The show bundle and the show l2vpn bridge-domain commands are used to verify that the router was
• The ACs in this example use interfaces that are in the admin down state.
