Configuring Static Routes on the Switch
Note For information on configuring a default gateway (default route), see the “Configuring the Default
Gateways” section on page 3-8.
In some situations, you might need to add a static routing table entry for one or more destination
networks. The static route entries consist of the destination IP network address, the IP address of the next
hop router, and the metric (hop count) for the route.
The destination IP network address can be variably subnetted to support Classless Interdomain Routing
(CIDR). You can specify the subnet mask (netmask) for a destination network using the number of subnet
bits or using the subnet mask in dotted decimal format. If no subnet mask is specified, the default
(classful) mask is used.
The switch forwards the IP traffic that is generated by the switch using the longest address match in the
IP routing table. The switch does not use the IP routing table to forward the traffic from the connected
devices, only the IP traffic that is generated by the switch itself (for example, Telnet, TFTP, and ping).
To configure a static route, perform this task in privileged mode:
This example shows how to configure a static route on the switch and verify that the route is configured
properly in the routing table:
Console> (enable) set ip route 172.16.16.0/20 172.20.52.127
Route added.
Console> (enable) show ip route
