Configuring Static Routes
A static route is an IP address that you manually configure and that the routing protocol does not learn,
such as open shortest path first (OSPF). Often, static routes are used as backup routes in case other
dynamically learned routes are unreachable.
You can enter as many static IP addresses as necessary.
To configure a static route, use the following command.
• Configure a static IP address.
CONFIGURATION mode
ip route [vrf vrf-name] ip-address mask {ip-address | interface [ip-address]}
[distance] [permanent] [tag tag-value] [vrf vrf-name]
Use the following required and optional parameters:
– vrf vrf-name : use the VRF option after the ip route keyword to configure a static route on
that particular VRF, use the VRF option after the next hop to specify which VRF the next hop
belongs to. This will be used in route leaking cases.
NOTE: For more information on route leaking, see the Route Leaking Between VRFs section.
– ip-address: enter an address in dotted decimal format (A.B.C.D).
– mask: enter a mask in slash prefix-length format (/X).
– interface: enter an interface type then the slot/port information.
– distance: the range is from 1 to 255. (optional)
– permanent: keep the static route in the routing table (if you use the interface option) even if
you disable the interface with the route. (optional)
– tag tag-value: the range is from 1 to 4294967295. (optional)
Example of the show ip route static Command
To view the configured routes, use the show ip route static command.
