Examining Interior Routers
As you learned earlier in this hour, interior routers operate within an autonomous network. An interior router should have complete knowledge of any network segments attached to other routers within its group, but it does not need complete knowledge of networks beyond the autonomous system.
Several interior routing protocols are available. A network administrator must choose an interior routing protocol appropriate for the conditions of the network and compatible with the network hardware. The following sections discuss the important interior routing protocols:
Routing Information Protocol (RIP)
Open Shortest Path First (OSPF)
RIP is a distance vector protocol, and OSPF is a link state protocol. In each case, the real ...
