A bridge group is created on Router A. Ethernet 2/0/1 in LAN 1 and Ethernet 2/0/2 in LAN 2
are added to the bridge group. In this manner, LAN 1 and LAN 2 are bridged and can
communicate with each other at the link layer.
After local bridging is configured, the bridge group configured for the transparent bridge is able
to:
l Learn the mapping relationship between the MAC address and the interface (MAC
forwarding entry).
l Be configured with static and blackhole MAC address entries.
l Be enabled with or disabled from dynamic MAC address entry learning.
l Be configured with the aging time of dynamic MAC entries.
l Bridge all protocol packets (including IP and non-IP packets) by default.
9.2.3 Remote Bridging
If LANs in different geographical locations need to communicate with each other at the link
layer, remote bridging can be used to bridge the LANs.
