Dell S3100 EMC Command Line Reference Guide for the Series 9.14.2.5 - Page 1586

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. 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. Related 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 Parameters ipv6 route-import tag [route-map-name] route-import tag route-map-name Enter the keywords route-import to import IPv6 routes into the VRF. 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. 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.

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 the protocol and prefix-list options. Other options that you configure in the route-maps are ignored. 1586 Virtual Routing and Forwarding (VRF)
