Usage Information To export all the routes corresponding to a source VRF, use the ip route-export tag command without
specifying the route-map attribute. This action exposes source VRF routes to other VRFs, which then import these
routes using the ip route-import tag command.
In Dell Networking OS, you can congure one route-export per VRF as you can only expose one set of routes for
leaking. However, you can congure 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 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
• ipv6 route-import – imports IPv6 routes from another VRF.
ipv6 route-import
Imports IPv6 routes that another VRF leaks using the tag that VRF species during export of these routes.
Syntax
ipv6 route-import tag [route-map-name]
Parameters
route-import Enter the keywords route-import to import IPv6 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.
