[ns] Mobile IP & RSVP help!!!

[Prashant Ratanchandani <nsprc@yahoo.com>]

Dear all,
I was attempting to make certain changes to ns-mip.tcl
in order to include RSVP.Since MIPBS and MIPMH are
actually extensions of wireless nodes and the earliest
implementation of mobile IP uses these nodes and
creates link I tried to substitute the links that are
dynamically created  by the MIPMH with the MIPBS by
duplex-rsvp-links.
However not the validation test input gives the foll.
error-
