CLI Guide

In Dell Networking OS, you can configure one route-export per VRF as you can
only expose one set of routes 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. 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 specified
filtering options to match BGP, the BGP route is not leaked as that route is not
active in the Source VRF.

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 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.
