`ip route interface`

Syntax

ip route <IPv4 ADDR/MEMBER> interface <IPv4 ADDR>
 [<DISTANCE> | <VRF INSTANCE-NAME>]

no ip route

Description

Creates a route leak between the SRC-VRF and DST-VRF. Using the static method, the route must first be added to the destination VRF. The route is added to the local interface of the source VRF with a next-hop interface. The existing IP route command can then take either the next-hop IP or the next-hop interface.

INTERFACE refers to the outgoing interface in an m/s/p format
Users must provide both the next-hop IP and the interface information to leak network routes.
The next-hop IP information is not required to leak connected routes.

The [no] form of command deletes the static VRF leaked route.

Command context

config

Parameters

<IPv4 ADDR/MEMBER>: Required: IPv4 IP-Address route destination.
<IPv4 ADDR>: Required: IPv4 route destination
<DISTANCE>: Optional: administrative distance of static route
<VRF INSTANCE-NAME>: Optional: VRF instance

Options

blackhole: Discard packets to the destined route silently.
reject: Discard packets to the destined route and return ICMP error to the sender.

Authority

Administrators or local user group members with execution rights for this command.
