ip route-export
Enables route leaking between VRFs. This command exports or shares IPv4 routes corresponding to one VRF with other
nondefault VRFs.
Syntax
ip 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 (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 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.

Usage
Information
To export all the routes corresponding to a source VRF, you can use the ip route-export tag
command without specifying the route-map attribute. This action exposes source VRF routes to various
other VRFs, which then import these routes using the ip route-import tag command.
In Dell EMC 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.
