Local Bridging

Local Bridging

Local bridging is the basic function of transparent bridging. As shown in Figure 15-5, LAN 1 and LAN 2 are in the same geographic location and need to communicate with each other at the link layer. Transparent bridging can be used to bridge these LANs locally.

Figure 15-5  Local bridging network diagram

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:

  • Learn the mapping relationship between the MAC address and the interface (MAC forwarding entry).

  • Be configured with static and blackhole MAC address entries.

  • Be enabled with or disabled from dynamic MAC address entry learning.

  • Be configured with the aging time of dynamic MAC entries.

  • Bridge all protocol packets (including IP and non-IP packets) by default.
