Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# interface BDI3
Router(config-if)# encapsulation dot1Q 1 second-dot1q 2
Router(config-if)# ip address 2.2
.2.1 255.255.255.0
Router(config-if)# mac-address 1.
1.3
Router(config-if)# no shut
Command or Action Purpose
Step 1
configure terminal

Step 3
encapsulation encapsulation dot1q <first-tag>
[second-dot1q <second-tag>]
Example:
Router(config-if)#encapsulation dot1Q 1
second-dot1q 2
Defines the encapsulation type.
The example shows how to define dot1q as the

[default]}
Example:
Router(config-if)# ip address 2.2.2.1
255.255.255.0
Specifies either the IPv4 or IPv6 address for the bridge

Step 5
mac-address {mac-address}
Router(config-if)# mac-address 1.1.
3
Specifies the MAC address for the bridge domain
interface.
Step 6
no shut
Example:
hostname(config-if)# no shut
Enables the bridge domain interface on the Cisco ASR
