Multicast Questions
Hello.
My first question :
It seems like "$ns set-address-format expanded" and multicast
do not go together. When I use expanded address I get errors similar to "_o57:
no target for slot 128". This error occurs when I generate only 100 nodes with
expanded address format, but not without expanded address format. Anyone knows
anything about this?
My second question :
Is there any way I can see routes from source to destination nodes in
multicast? I tried following :
set mproto DM
set mrthandle [$ns mrtproto $mproto {}]
........
$ns join-group receiver_agent group
$ns get-mcast-tree $node($src) $group #src is srouce node id
I do not get multicast tree but following error messages.
ns: _o3 get-mcast-tree _o53 0x8002]: can't read "GROUP_": no such variable
while executing
"error "No replicator for $GROUP_ at [$src id]""
(procedure "_o3" line 7)
(Simulator get-mcast-tree line 7)
invoked from within
"_o3 get-mcast-tree _o53 0x8002]"
Any help is greatly appreciated.
Thanks in advance.
