Configuring Fallback Bridging
Beginning in privileged EXEC mode, follow these steps to create a bridge group and to assign an
interface to it. This procedure is required.
Command
Step 1
configure terminal
Step 2
bridge bridge-group protocol
vlan-bridge
Step 3
interface interface-id
Step 4
bridge-group bridge-group
Step 5
end
Step 6
show running-config
Step 7
copy running-config startup-config
To remove a bridge group, use the no bridge bridge-group global configuration command. The no
bridge bridge-group command automatically removes all SVIs and routes ports from that bridge group.
To remove an interface from a bridge group and to remove the bridge group, use the no bridge-group
bridge-group interface configuration command.
This example shows how to create bridge group 10, to specify that the VLAN-bridge STP runs in the
bridge group, to define a port as a routed port, and to assign the port to the bridge group:
Switch(config)# bridge 10 protocol vlan-bridge
Switch(config)# interface gigabitethernet3/0/1
Switch(config-if)# no switchport
Switch(config-if)# no shutdown
Switch(config-if)# bridge-group 10
This example shows how to create bridge group 10 and to specify that the VLAN-bridge STP runs in the
bridge group. It defines an SVI for VLAN 2 and assigns it to the bridge group:
Switch(config)# bridge 10 protocol vlan-bridge
Switch(config)# vlan 2
Switch(config-vlan)# exit
Switch(config)# interface vlan2
OL-12247-01
Purpose
Enter global configuration mode.
Assign a bridge group number, and specify the VLAN-bridge
spanning-tree protocol to run in the bridge group. The ibm and dec
keywords are not supported.
For bridge-group, specify the bridge group number. The range is 1
to 255. You can create up to 32 bridge groups.
Frames are bridged only among interfaces in the same group.
Specify the interface on which you want to assign the bridge group, and
enter interface configuration mode.
The specified interface must be one of these:
•
A routed port: a physical port that you have configured as a Layer 3
port by entering the no switchport interface configuration
command.
•
An SVI: a VLAN interface that you created by using the interface
vlan vlan-id global configuration command.
Note
You can assign an IP address to the routed port or to the SVI,
but it is not required.
Assign the interface to the bridge group created in Step 2.
By default, the interface is not assigned to any bridge group. An
interface can be assigned to only one bridge group.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
