Users Guide

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 lter leaked routes from each source VRF. For example, 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 specied ltering options to match BGP, the BGP route is not leaked as that route is not active in the Source
VRF.
Related Commands
• ip route-import — imports routes from another VRF.
ip route-import
Imports IPv4 routes that another VRF leaks using the VRF tag during the export of these routes.
Syntax
ip route-import tag [route-map—name]
Parameters
route-import Enter the keywords route-import to import routes into the 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, use the same ASN number that is specied as
the export route target at the source VRF.
route-map-name Enter the name of the route-map to lter the imported routes.
NOTE: Use the route-map attribute while importing routes from the global
RTM. Route-maps allow you to lter routes at the import end based on the
matching criteria that you dene in the route-map.

Usage Information It is possible to congure multiple import conditions per VRF depending on the exporting VRF.

that are congured in the route-maps are ignored.
