Re: NS 2.1b3 / nam-trace error?

[Ya Xu <yaxu@ISI.EDU>]

Please download the current nam to try.

Also, sun's mobileIP was just integrated into current ns snapshot. You can
find an example at tcl/ex/miptest.tcl which creates a nam tracefile called
miptest.nam. You can use the current nam to play it.

thanks

Ya
