Reference Guide

to a default VRF, remove VRF association from the interface. You can use this only
if there is no IP address configured on the interface.
There must be no prior Layer 3 configuration on the interface when configuring
VRF.
VRF must be enabled prior to implementing this command.
You can configure an IP subnet or address on a physical or VLAN interface that
overlaps the same IP subnet or address configured on another interface only if the
interfaces are assigned to different VRFs. If two interfaces are assigned to the same
VRF, you cannot configure overlapping IP subnets or the same IP address on them.
ip route-export
Enable route leaking between VRFs. Export or share IPv4 routes corresponding to one VRF with other
non-default VRFs.
C9000 Series
Syntax
ip route-export tag [route-map-name]
Parameters
route-export Enter the route-export keyword to leak or share routes
between VRFs.
tag Enter a tag (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.
route-map-name (Optional) Enter the name of the route-map to filter the
exported routes.
You can leak global routes for VRF. As the global RTM
usually contains a large pool of routes, when the destination
VRF imports global routes, these routes are 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.
