disconnecting a node from a LAN in ns

[Guruprasad Bhaskar <bguru@utdallas.edu>]

Hi,

I created a LAN with say, 3 nodes using "make-lan" command in ns-2.1b5. I
then initiated a TCP
session with an external node (connected to the LAN through another
node) as the source and one of the LAN nodes as the sink. After the
session starts, I am not able to make the "vlink" ( which connects the
TCP sink and the LAN) down. I am able to obtain the id of this vlink but
the command "$link(src_id:dst_id) down" does not help. But with this
command I am able to make the link down only before the TCP session
starts, not after that. 

I would appreciate it if anybody can help me out of this problem,

Thanx,

Guru.
