Hoi Mustafa,
I don't know much about memif, but seeing as it creates an L2 device, one
avenue is adding the memif into a bridge-domain together with a transport
tunnel, for example VXLAN:
vpp# create interface memif id 0 master
vpp# create bridge-domain 10
vpp# create vxlan tunnel src 192.168.11.3 dst 192.168.11.0 vni 10
vpp# set interface l2 bridge memif0/0 10
vpp# set interface l2 bridge vxlan_tunnel0 10
vpp# set interface state vxlan_tunnel0 up
vpp# set interface state memif0/0 up
vpp# show bridge-domain 10 detail

If you'd do this on both sides (ie a reciprocal tunnel on 192.168.11.0
pointed at 11.3 with the same VNI id 10), I think you would get
bidirectional forwarding of the memif0/0 payload between both VPP instances.

Pim
