ON, and Z9500.

Usage

You can use the ip route-export tag command without specifying the route-map

Information

attribute to export all the routes corresponding to a source VRF. This action

 

exposes source VRF's routes to various other VRFs, which then import these routes

 

using the ip route-import tag command. In Dell Networking OS, you can configure

 

at most one route-export per VRF as only one set of routes can be exposed for

 

leaking. However, you can configure multiple route-import targets because a VRF

 

can accept routes from multiple VRFs.

 

You can expose a unique set of routes from the Source VRF for Leaking to other

 

VRFs. When two VRFs leak or export routes, there is no option to discretely filter

 

leaked routes from each source VRF. Meaning, you cannot import one set of routes

 

from one VRF and another set of routes from another VRF.

 

Only Active routes are eligible for leaking. For example, if one VRF has two routes

 

corresponding to BGP and OSPF, in which the BGP route is not active, the OSPF

 

route takes precedence over BGP. Even though the Target VRF has specified

 

filtering options to match BGP, the BGP route is not leaked as that route is not

 

active in the Source VRF.

ip route-import tag [route-map—name]

Parameters

route-import

VRF.

 

tag

Enter a tag (ASN number) to specify an import route target

 

 

for importing routes from another VRF.

 

 

To import leaked routes from another VRF, you must use the
