dynamic routing protocols. The preference also controls whether a static route is more or less preferred than other static routes to the same destination. The ip route command optionally configures a route in the selected VRF. The IP route command can set a value for the route preference. Among routes to the same destination, the route with the lowest preference value is the route entered into the forwarding database. Specifying the preference of a static route controls whether a static route is more or less preferred than routes from dynamic routing protocols. The preference also controls whether a static route is more or less preferred than other static routes to the same destination. This command creates a static route in a specified virtual router instance referred to by name 'vrf-name' by taking an optional vrf argument. If the nexthop interface argument is given without specifying a nexthopip, it is added as a static interface route. If the next-hop interface is in the default routing domain, they routes are identified as leaked routes in the virtual router table. The VRF identified in the parameter must have been previously created or an error is returned. Route leaking in VRFs is only supported to or from the default routing instance and only for static routes. Configuring a leaked route from a nondefault VRF to another non-default VRF results in undefined behavior. Only IPv4 routes are supported with the vrf parameter. Adding a static route with a Null 0 next hop specified configures a routing black hole (a static reject route). Packets destined to that prefix are dropped. If an interface for the next hop is specified, it may be a numbered or unnumbered interface. A static route entry is only installed if the next hop IP address matches one of the local subnets (i.e., the next hop is reachable). In case of unnumbered interfaces, static routes entries created for an unnumbered-peer do not match with any of the local subnets. By specifying the interface explicitly in the static route command along with the next hop IP address, the switch can correctly install static route entries for unnumbered-peers. It is also possible to configure 'unnumbered interface routes' where the next hop IP address is not specified and only the unnumbered nexthop interface is configured. Layer 3 Routing Commands 1553
