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.

Some switches (such as the Aruba 8400 Switch Series), use the format member/slot/port (for example, 1/1/1).

<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.
