[ns] Implementing multiple interfaces in ns-2.33

[Jong Bum Ryou]

Dear ns-users and al ch

I am also trying to apply Ramon's multi-interface procedure in ns-2.33.

However, I have a problem with CH.5

There is no exact direction where the new codes should add in the  
chosen routing agent.

Is any body who can help this problem ?

Thax in advance.
