[ns] Simulation clock not moving ahead

[Manaswi Saha]

Hello everyone,

I have implemented a new multicast routing protocol for wireless mesh
networks in ns2.33.
It is successfully attached.

When I run the TCL file, the simulation marked for 0.00000000 time works
but all the others do not work.

i.e.

$ns_ at 0.000000000000 "[$meshrouter_($i) agent 255] add-router"
  ----- Works

but

$ns_ at 0.000000000000 "[$meshrouter_($i) agent 255] brid $i"
