Typical Bridge Configuration 311

Transparent Bridging for	I. Networking Requirements
Asynchronous Dial-in	Configure transparent bridging for asynchronous dial-in standby on two routers.
Standby
	Thereby, transparent bridging can be implemented by enabling asynchronous
	dial-in in case that the serial interfaces through which the routers are directly
	connected are failed.
