pool of routes, when the destination VRF imports global
routes, these routes will be duplicated into the VRF's RTM.
As a result, it is mandatory to use route-maps to filter out
leaked routes while sharing global routes with VRFs.

Usage Information You can use the ip route-export tag command without specifying the route-
map attribute to export all the routes corresponding to a source VRF. This action
exposes source VRF's routes to various other VRFs, which then import these routes
using the ip route-import tag command. In Dell Networking OS, you can
configure at most one route-export per VRF as only one set of routes is exposed
for leaking. However, you can configure multiple route-import targets because a
VRF accepts 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. 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.
