Configuring Static Routes

About this task

Configure a static route when you want to manually create a route to a destination IP address.

Note

When you configure a static route with a next-hop-vrf context, you can specify a next-hop IP address that is a locally owned VRRP IP address of the system itself. However, this is not a supported configuration. The best practice is to implement an alternative method of inter-vrf route sharing, such as route redistribution or ISIS accept polices.

If a black hole route is enabled, you must first delete or disable it before you can add a regular static route to that destination.

For route scaling information and for information on the maximum number of static routes supported on your hardware platform, see Release Notes for VOSS.

Note

As a best practice, do not configure static routes on a DvR Leaf node unless the configuration is for reachability to a management network using a Brouter port.

You cannot configure the preference of static routes on a Leaf node.

1. Enter either Global Configuration mode or VRF Router Configuration mode for a specific VRF context:

   enable

   configure terminal

   Optional: router vrf WORD<1-16>

2. Create an IP static route:

   ip route <A.B.C.D> <A.B.C.D> <A.B.C.D> weight <1–65535>

3. Enable an IP static route:

   ip route <A.B.C.D> <A.B.C.D> <A.B.C.D> enable

4. Use the following variable definitions table to configure other static route parameters as required.
5. View existing IP static routes for the device, or for a specific network or subnet:

   show ip route static

6. Delete a static route:

   no ip route <A.B.C.D> <A.B.C.D> <A.B.C.D>

Example

Create an IP static route, enable a static route, and view the existing IP static routes for the device, or for a specific network or subnet.
