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 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.
