Hi I am a novice in NS2 and I try to set a MultiPath routing scenerios I have node N0->N1 N0->N2 N1->N3 N2->N3 I want node from N0-N1 to take both the N0->N1->N3 path and the N0->N2->N3. This should be somthing basic that can be done without modifying or adding classes. Poring over teh documentation I cannot figure how to do that. Can someone help ??
