Users Guide

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
specified as the export route target at the source VRF.
route-map-name Enter the name of the route-map to filter the imported routes.
NOTE: Use the route-map attribute while importing routes from the global
RTM. Route-maps allow you to filter routes at the import end based on the
matching criteria that you define in the route-map.

Commands
• ip route-export – exports routes to another VRF.
ipv6 route-export
Enables route leaking between VRFs. This command exports or shares IPv6 routes corresponding to one VRF with other
nondefault VRFs.
Syntax
ipv6 route-export tag [route-map-name]
Parameters
route-export Enter the keywords route-export to leak or share routes between VRFs.
tag Enter a tag (ASN number) as the export route target to expose routes to other
VRFs. This tag acts as an identifier for exported routes. Use this identifier while
importing these routes into another nondefault VRF.
route-map-name (Optional) Enter the name of the route-map to filter the exported routes. You can
leak global routes to be made available to VRFs. As the global RTM usually
contains a large pool of routes, when the destination VRF imports global routes,
these routes are duplicated into the VRF's RTM. It is mandatory to use route-maps
to filter out leaked routes while sharing global routes with VRFs.
