Dell 6200 SERIES manual Example 1 Configure Administrative Preferences

Example 1: Configure Administrative Preferences

The following commands configure the administrative preference for the RIP and OSPF:

console#Config router rip

distance rip 130 exit

For OSPF, an additional parameter identifies the type of OSPF route that the preference value applies to:

router ospf distance ospf ?

external	Enter preference value			for OSPF external routes.
inter-area	Enter	preference	value	for	inter-area	routes.
intra-area	Enter	preference	value	for	intra-area	routes.

distance ospf inter 170 exit

Example 2: Assigning Administrative Preferences to Static Routes

By default, static routes are assigned a preference value of 1. The following command changes this default:

console#Config

ip route distance 20 exit

When you configure a static route, you can assign a preference value to it. The preference overrides the setting inherited as the default value for static routes.

In this example, two static routes are defined to the same destination but with different next hops and different preferences (25 and 30). The route with the higher preference will only be used when the preferred route is unavailable:

console#Config

ip route 10.25.67.0 255.255.255.0 10.25.22.2 ip route 10.25.67.0 255.255.255.0 10.25.21.0 exit

Similarly, you can create two default routes—one preferred and the other used as a backup. In this example, the preference values 1 and 10 are assigned:

console#Config

ip route default 10.25.67.2 1 ip route default 10.25.67.7 10 exit
