IP Routing Features

Configuring Static IP Routes

This feature allows the routing switch to adjust to changes in network

topology. The routing switch does not continue trying to use routes on

unavailable paths but instead uses routes only when their paths are available.

Configuring a Static IP Route

To configure an static IP route with a destination network of

192.0.0.0 255.0.0.0 and a next-hop router IP address of 195.1.1.1, you would

enter the following commands:

ProCurve(config)# ip route 192.0.0.0 255.0.0.0 195.1.1.1

ProCurve(config)# write memory

Syntax: ip route < dest-ip-addr > < dest-mask > < next-hop-ip-addr >

— or —

ip route < dest-ip-addr >/< mask-bits > < next-hop-ip-addr >

The < dest-ip-addr > is the route’s destination.

The < dest-mask > parameter specifies the subnet mask for the routes destina-

tion IP address. Ones are significant bits and zeros allow any value. For

example, the mask 255.255.255.0 matches all hosts within the Class C sub-net

address specified by the < dest-ip-addr >. Alternatively, you can use CIDR

notation and specify the number of bits in the network mask. For example,

you can enter 209.157.22.0/24 instead of 209.157.22.0 255.255.255.0.

The < next-hop-ip-addr > is the IP address of the next router in the path to the

destination.

Note The switch allows one static route configured for a particular network desti-

nation. If you configure a static route to a given network and then later

configure a different static route to the same network, the switch replaces the

first static route with the second.

Configuring the Default Route

You can also assign a default route and enter it in the routing table. The default

route is the route assigned to all traffic that has network destinations that are

not in the local routing table. For example, if 208.45.228.35 is the IP address

of your ISP router, all non-local traffic could be directed to that route by

entering the commands:

ProCurve(config)# ip route 0.0.0.0 0.0.0.0 208.45.228.35

ProCurve(config)# write memory
