Hi,

I would like to know whether fhmipv6 extension in ns2 that is originally developed my Robert Hsieh support multicasting? I want to generate a wired-cum wireless dumbbell topology that have 2 CN nodes and 2 MN nodes?

Before handover operation, packets are transmitted towards the 2 MN nodes that are located in home network. However, when the handover operation is about to occur,I get these error when trying to simulate multicasting using the fhmipv6:

--- Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl) ---
_o33: no target for slot 0
_o33 type: Classifier/Addr
content dump:
classifier _o33
0 offset
0 shift
2047 mask
1 slots
slot 1: _o35 (Classifier/Port/Reserve)
---------- Finished standard no-slot{} default handler -----

After the handover operation, ns2 does not know where to send d packet as there is no nodes created.

That is why i am doubting wheter FHMIPV6 extension in ns2 support multicasting or not...
