Functionalities
When Host A sends an Ethernet frame to Host C, if the bridge does not find a
■
MAC-to-interface mapping about Host C in its bridge table, the bridge
forwards the Ethernet frame to all interfaces except the interface on which the
frame was received, as shown in
Figure 111 The proper MAC-to-interface mapping is not found in the bridge table

CAUTION: When a bridge receives a broadcast or multicast frame, it forwards the
frame to all interfaces other than the receiving interface.
Complete these tasks to configure bridging:

When configuring transparent bridging over ATM, you need to enable
■
transmission and receiving of bridged frames on the PVC.
When configuring transparent bridging over PPP, you need to configure PPP on
■
the corresponding interface as the link layer protocol for interface
encapsulation.
When configuring transparent bridging over multilink PPP (MP), you need to
■
configure PPP on the corresponding interface as the link layer protocol for
interface encapsulation, create a virtual template interface and associate the
physical interface with the virtual template interface.
