Fall Back Bridge Example

 

!-----啟動Integrated Routing and Bridging模式
bridge irb

! -----指定Bridge-Group 1 (Fa0/0介面界接SW1 VLAN 10)
interface FastEthernet0/0
no ip address
bridge-group 1

!-----指定Bridge-Group 1 (Fa0/0介面界接SW2 VLAN 20)
interface FastEthernet0/1
no ip address
bridge-group 1

! -----建立Bridge Virtual Interface
interface BVI1
ip address 192.168.1.254 255.255.255.0

! -----指定Bridge-Group的封裝模式為802.1q
bridge 1 protocol ieee

!-----指定Bridge-Group的Routing模式為IP Routing
bridge 1 route ip
