When u say that option 2 worked for u that means in ur case 150.1.1.1 was
reachable from 150.2.2.2 and vice versa as well ( ping 150.1.1.1 sou
150.2.2.2) would have worked ,, thats why tunnel came UP.
In 2md case which didnt worked for u .... ping 154.1.23.2 sou 150.1.1.1
would not have been through .. thats why tunnel didnt came UP .
So the point here is dest shd be reachable from src ..
