Command
Step 5
Router(config-subif)# encap dot1q
vlan - number
Step 6
Router(config-subif)# bridge-group
bridge-group - number
Step 7
Router(config-subif)# end
Step 8
Router# copy running-config startup-config
In a bridge group on the ML-Series card, the VLAN ID does not have to be uniform across interfaces
Note
that belong to that bridge group. For example, a bridge-group can connect from a VLAN ID subinterface
to a subinterface with a different VLAN ID, and then frames entering with one VLAN ID can be changed
to exit with a different VLAN ID. This is know as VLAN translation.
IP routing is enabled by default. To enable bridging, enter the no ip routing or bridge IRB command.
Note
Native VLAN frames transmitted on the interface are normally untagged. All untagged frames received
Note
on the interface are associated with the native VLAN, which is always VLAN 1. Use the command
encapsulation dot1q 1 native.

IEEE 802.1Q VLAN Configuration

The VLAN configuration example for the ML100T-12 shown in
VLANs:
•
•
•
•
Fast Ethernet subinterface 0.1 is in the IEEE 802.1Q native VLAN 1.
Fast Ethernet subinterface 0.2 is in the IEEE 802.1Q VLAN 2.
Fast Ethernet subinterface 0.3 is in the IEEE 802.1Q VLAN 3.
Fast Ethernet subinterface 0.4 is in the IEEE 802.1Q VLAN 4.

IEEE 802.1Q VLAN Configuration
Purpose
Sets the encapsulation on the VLAN to IEEE
802.1Q.
Assigns a network interface to a bridge group.
Returns to privileged EXEC mode.
(Optional) Saves your configuration changes to
NVRAM.
