Routing protocols for the corporate network

The following section describes the use of OSPF as the IP routing protocol for this corporate network scenario.

IP routing protocols

Corporate networks typically use the OSPF protocol because it is efficient in large networks. For this corporate network scenario, OSPF is configured on all the servers running Routing and Remote Access within the corporate site. Different types of routes are used depending on the type of WAN connection. For a demand-dial link, you must use either static routes or auto-static routes that use RIP. For dedicated WAN links, you can use static routes, RIP, or OSPF.

For this scenario, Routers 5, 6, 7, 9, and 10 are also configured with either static routes or RIP version 2 on the interfaces that are not configured for OSPF. Static routes are preferable to using RIP version 2 when the link bandwidth is not adequate or when routing update traffic is considered an unnecessary overhead cost.
