[FROG] BGP unnumbered

   Is the bgp unnumbered feature broken from version 5.0? I checked in
version 6 , I see the bgp neighborship established with unnumbered and if I
advertise the routes its showing ipv4 address as next hop instead of
interface ID/IPv6 Link local. Below are the show outputs and the running
configurations of one of the system. Can somebody please help me out? Am i
missing something?

show ip bgp summary
