310CHAPTER 19: CONFIGURING BRIDGE

Transparent Bridging for Synchronous Dial-in Standby

I. Networking Requirements

Configure transparent bridging for synchronous dial-in standby on two routers. Thereby, transparent bridging can be implemented by enabling synchronous dial-in in case that the serial interfaces through which the routers are directly connected are failed.
