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 can be exposed 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. 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 specified
filtering options to match BGP, the BGP route is not leaked as that route is not
active in the Source VRF.
