l If the Bridge-if interface is Down, troubleshoot the member interfaces in the bridge group.
For example, check whether the interface is up and the protocol configuration is correct.
l If the Bridge-if interface is Up, go to Step 3.
Step 3 Check that the routes between different bridge groups are reachable.
Run the Ping command on Router A to check whether different bridge groups can ping each
other successfully.
l If the ping fails, go to Step 4.
l If the ping succeeds, go to Step 5.
Step 4 Check that IP routing is enabled for the bridge group.
Run the display bridge information command on Router A to check information about the
configured bridge group.
<RouterA> display bridge information
Bridge 1 :
Status : Undo Shutdown
Bridging : IP, Others
Routing : IP
MAC learning : Enable
interface :total 2 interface(s) in the bridge
Ethernet1/0/0 : Up
Ethernet2/0/0 : Up
Bridge 2 :
Status : Undo Shutdown
Bridging : IP, Others
Routing : IP
MAC learning : Enable
interface :total 1 interface(s) in the bridge
Ethernet2/0/1 : Up
l If IP routing is not enabled for the bridge group, run the routing ip command in the bridge
group view to enable IP routing.
l If IP routing has been enabled for the bridge group, check whether the IP address is correctly
configured for the Bridge-if interface. For details, see the chapter "The Ping Operation
Fails" in the AR2200-S Troubleshooting - IP Forwarding and Routing.
If different bridge groups still cannot ping each other successfully after the preceding steps are
complete, go to Step 5.
Step 5 Check that the network-side interfaces on Router A and Router B are added to the same bridge
group.
Run the display this command on Router A and Router B to check the configuration on network-
side interfaces.
# Check the network-side interface configuration on Router A.
<RouterA> system-view
[RouterA] interface ethernet2/0/1
[RouterA-Ethernet2/0/1] display this
