I don’t know, never tried. I would suggest though enabling an interface for 
receiving IP packets the ‘standard way’

Hi Neale,

Can you not also do:
comment { ingress direction }
set interface feature loop0 ip4-lookup arc ip4-unicast  disable
comment { egress direction }
set interface feature loop0 arp-reply arc arp disable

hi,

to enables IP4 forwarding on an interface, either apply an address or make it 
unnumberered to another interface (that has an address);
   set int ip addr <INT> <ADDR>
   set int unnumbered <INT> use <INT2>
to enables IP4 forwarding on an interface, either apply an address or enable 
ip6 on it.
   set int ip addr <INT> <ADDR>
   enable ip6 <INT>

May I know if VPP has any command to individually enable/disable ip forwarding 
per interface level.

Thanks
