i tried running the mobile ipv6 scenario i ran for the mobile ipv4 using the
scripts below but i got an error "segmentation fault (core dumped)"when i tried
running the simulation.what do u think is the problem
thanks

[ns] Mobile IPv6
Hi everyone! I am looking to implement MIPv6 in NS-2. I have seen a few posts and they say I need to install MobiWan (which works only with NS-2.1b6). Can I not use Mobiwan (or anything else in NS-2) for implementing MIPv6? Your help will be, as always, highly appreciated Faraz
