Figure 3-1 shows a typical Cisco
®
router with a serial interface configured as a PPP
half-bridge. The router serial interface uses a remote device that supports PPP
bridging to function as a node on the remote Ethernet network. The serial
interface on the Cisco router will have an IP address on the same Ethernet subnet
as the bridge.
