ip route-export
Enables route leaking between VRFs. Exports or shares IPv4 routes corresponding to one VRF with other non-default VRFs.
Syntax
ip route-export tag [route-map-name]
Parameters
route-export Enter the keyword 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 identier for exported routes. You can use this identier while importing these
routes into another non-default VRF.
route-map-name (Optional) Enter the name of the route-map to lter the exported routes.
You can leak global routes to be made available to VRFs. As the global RTM usually
contains a large 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 lter out leaked routes while sharing global routes with VRFs.

Version Description
9.7(0.0) Introduced on the S4810, S4820T, S5000, S6000, S6000–ON, and Z9500.
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
congure at most one route-export per VRF as only one set of routes can be exposed 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. Meaning, you
cannot import one set of routes from one VRF and another set of routes from another VRF.
