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
congure at most one route-export per VRF as only one set of routes can be exposed for leaking. However,
you can congure 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.
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 specied ltering options to match BGP, the BGP route is not leaked as that route is not
active in the Source VRF.
Related Commands ip route-import – imports routes from another VRF.
ip route-import
Imports IPv4 routes that are leaked by another VRF using the tag specied by that VRF during export of these routes.
Syntax
ip route-import tag [route-map—name]
Parameters
route-import Enter the keyword route-import to import routes into the VRF.
tag Enter a tag (ASN number) to specify an import route target for importing routes
from another VRF.
To import leaked routes from another VRF, you must use the same ASN number
that is specied as the export route target at the source VRF.
route-map-name Enter the name of the route-map to lter the imported routes.
NOTE: You must use the route-map attribute while importing routes from
the global RTM. Route-maps enable you to lter routes at the import end
based on the matching criteria that you dene in the route-map.
