Creating a Bridge Group
To configure fallback bridging for a set of switched virtual interfaces (SVIs), these interfaces must be
assigned to bridge groups. All interfaces in the same group belong to the same bridge domain. Each SVI
can be assigned to only one bridge group.
Follow the steps below to create a bridge group and assign an interface to it.
SUMMARY STEPS
1. enable
2. configure terminal
3. no ip routing
4. bridge bridge-group protocol vlan-bridge
5. interface interface-id
6. bridge-group bridge-group
7. end
8. show vlan-bridge
9. show running-config
10. copy running-config startup-config
DETAILED STEPS
Command Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
no ip routing
Example:
Router(config)# no ip routing
Disables IP routing.
Step 4
bridge bridge-group protocol
vlan-bridge
Example:
Router(config)# bridge 100 protocol
vlan-bridge
Assigns a bridge group number and specifies 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.
• Frames are bridged only among interfaces in the same group.
