Dell C1048P Port Extender Networking Command-Line Reference Guide for the C900 - Page 2101

Version 9.8(0.0) 9.7(0.0) Description Introduced on the S3048-ON and S4048-ON. Introduced on the S4810, S4820T, S5000, S6000, S6000- ON, and Z9500. Usage Information Use theip 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 routes to various other VRFs, which then import these routes using the ip route-import tag command. In Dell Networking OS, you can configure only one route-export per VRF as only one set of routes can be exposed for leaking (or sharing). 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 sharing with other VRFs. When there are two VRFs 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 sharing. For example, if one VRF has two routes corresponding to BGP and OSPF, and the BGP route is inactive, the OSPF route takes precedence over BGP. The inactive BGP route is not shared even when the target VRF has the filtering options enabled to match BGP. Related Commands ip route-import - imports routes from another VRF. ip route-import Import IPv4 routes leaked by another VRF using the tag specified by that VRF during route-export process. C9000 Series Syntax Parameters ip route-import tag [route-map-name] route-import tag Enter the keyword route-import to import 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, you must 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.
