Usage
Information
Use this command to attach an interface to a configured VRF. You can attach an interface to either a
non-default VRF or a management VRF. To assign a port-back 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.
