Users Guide

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.

Commands
● ipv6 route-import – imports IPv6 routes from another VRF.
ipv6 route-import
Imports IPv6 routes that another VRF leaks using the tag that VRF specifies during export of these routes.
Syntax
ipv6 route-import tag [route-map-name]
Parameters
route-import Enter the keywords route-import to import IPv6 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, use the same ASN
number that is specified as the export route target at the source VRF.
route-map-name Enter the name of the route-map to filter the imported routes.
NOTE: Use the route-map attribute while importing routes from the global
RTM. Route-maps allow you to filter routes at the import end based on the
matching criteria that you define in the route-map.

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 the protocol and prefix-list options. Other
options that you configure in the route-maps are ignored.
