Dynamic Routing

Dynamic Routing uses protocols such as RIP and RIPv2 to automatically learn the route or next hop it must take based on the IP address of the destination contained in the datagram.

Campus-REX2 IP Addresses

Each Campus-REX2 unit has two IP addresses, the LAN address and the Line address. In the figure on page 131, the non-shaded side of the Campus-REX2 indicates the LAN address, which is for the Ethernet (10/100Base-T) connection. The shaded side of the Campus-REX2 is the IP Line address,
