Routing table

10.1.0.0/16 B

Figure 11-4. Prefix Lengths with Static Routing

You add routes to the routing table from the global configuration mode

context. Enter this command:

Syntax: ip route <destination network A.B.C.D> <subnet mask | /prefix length> <next

hop A.B.C.D | forwarding interface ID> [<administrative distance>]

Specifying administrative distance is optional. By default, static routes have

an administrative distance of 1 and are considered to be more reliable than

any other routes (except those to directly connected networks).

You should make the network address and subnet as short possible for the

next-hop address to still be valid for all matching packets. For example, to

configure a route to network 10.1.3.0 /24 on Router A shown in Figure 11-4,

you could enter a route to the entire 10.1.0.0 /16 network:

ProCurve(config)# ip route 10.1.0.0 255.255.0.0 10.1.1.2

You would have to configure a more specific route to network 10.1.3.0 /24 on

ProCurve(config)# ip route 10.1.3.0 255.255.255.0 10.1.30.2

For point-to-point connections, instead of the next-hop IP address, you can

specify the forwarding interface (for example, PPP 1 or Frame Relay 1.103).

It is often a good idea to specify the forwarding interface rather than the next-

hop address, particularly when connecting to an external network, because

IP addresses can change without notice.

The route in the routing table includes the forwarding interfaces, but allows

any next-hop neighbor that connects to the interface. See Figure 11-5.
