seems like you are asking about precursor list; you didn't specify which aodv implementation you are using, but most likely these rt-entries have .next attribute

Infact i don't wat to use precursor list, i use aodv which exist in ns 2.34, in aodv folder and in aodv.cc I uploaded it for you.at line 1216 you can see "ch->next_hop_ = rt->rt_nexthop;" . now i want to now command for 2nd node may be like this:
ch->next_hop_ = rt->rt_nexthop_nexthop; but this is not.

well, RREP do not contain sequences of next-hops, but next-hop counter

how I add this counter for second next hop?
