W2N-3.6-7401ASR-B#sh run int gig 0/0
Building configuration...

Current configuration : 146 bytes
!
interface GigabitEthernet0/0
 ip address 14.16.1.92 255.255.255.0
 tag-switching ip
end

The interface looks just like any other MPLS interface.

Just globally you would prevent labels for being exchanged
via 'tag-switching advertise-tags <acl>'.  What happens
in the forwarding path depends on the control plane being
set up and tags exchanged for the relevant prefixes.

In this scenario you can have ip and mpls packets going
in/out the same interface.
