I have this network:

NodeGroup1(172.16.100.2/25) <-Link1-> Node1(Link1 IP: 172.16.100.1/25 and LInkInter1 IP: 172.16.0.2/30)<-LinkInter1->
Node2(LinkInter1 IP: 172.16.0.1/30 and Link2 IP: 172.16.100.132/25)<-Link2->NodeGroup2(Link2 IP:172.16.100.129/25).

I want that traffic that goes from NodeGroup1 reaches NodeGroup2. I am thinkng in using the route command, but I don't know which values to use. Any help in using the route?

Here is the routing table:
NodeGroup1
