[ns] next hope at MAODV

[Albalas F \(AT\)]

Hi,

 

Can anyone explain to me what the following source line means (I am
working on MAODV).

 

aodv_nh_entry * nh = mt->mt_nexthops.lookup(ch->prev_hop_);

        if (nh == NULL || nh->enabled_flag != NH_ENABLE){

            if (nh) mt->mt_nexthops.remove(nh);

            Packet::free(p);

      }

 

These lines ar on aodv_mcast.cc file.

Please help.
