[ns] multiple interfaces in ns2

[Tatiana Polishchuk]

Hello,
I'm a new user of ns 2.33
I'm interested in constructing simulations for multihomed nodes, the hosts
with multiple interfaces (both wired and wireless). In fact I just need one
of the hosts to obtain 2 different IP addresses. NAM animation is also
desirable.
As far as I understand there is no such a functionality in the original
version of ns2.
Did anybody meet this problem? Any support in this case will be appreciated.
Please, help!
