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.
