Version Description
9.7(0.0) Introduced on the S4810, S4820T, S5000, S6000, S6000–ON, and Z9500.
Usage
Information
It is possible to configure multiple import conditions per VRF depending on the exporting VRF.
The export-target and import-target support only the match protocol and match prefix-list options. Other
options that are configured in the route-maps are ignored.

Commands
● ip route-export – exports routes to another VRF.
ipv6 route-export
Enables route leaking between VRFs. This command exports or shares IPv6 routes corresponding to one VRF with other
nondefault VRFs.
Syntax
ipv6 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 (ASN number) as the 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 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 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, use the ip route-export tag command
without specifying the route-map attribute. This action exposes source VRF routes to 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.
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.
