Parameters route-export tag route-map-name Enter the keyword route-export to leak or share routes between VRFs. 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. You can use this identifier while importing these routes into another non-default VRF. (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 will be duplicated into the VRF's RTM. As a result, it is mandatory to use route-maps to filter out leaked routes while sharing global routes with VRFs. Defaults N/A Command Modes VRF MODE CONFIGURATION Command History Version 9.9(0.0) 9.8(0.0) 9.7(0.0) Description Introducued on the C9010. Introduced on the S3048-ON and S4048-ON. 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 configure at most one route-export per VRF as only one set of routes is exposed for leaking. However, you can configure multiple route-import targets because a VRF accepts 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. 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 Import IPv6 routes leaked by another VRF using the tag specified by that VRF during export of these routes. C9000 Series Syntax Parameters ipv6 route-import tag [route-map-name] route-import Enter the keyword route-import to import IPv6 routes into the VRF. Virtual Routing and Forwarding (VRF) 1902
