Information
There must be no prior Layer 3 configuration on the interface when configuring VRF.
VRF must be enabled prior to implementing this command.
Starting in release 8.4.1.0, 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.
