RE: [ns] OSPF implementation

["Mark Puddephatt" <m.c.puddephatt@pgr.salford.ac.uk>]

Hi all,

I have been trying to run the linkstate stuff, and have encountered the
following: can anyone please help (most likely I'm doing something/not doing
something simple here...)

$ ns simple-eqp1.tcl
can't read "addr_": no such variable
	while executing
"subst $[subst $var"
	(procedure "_o159" line 5)
	(Object next line 5)
	invlked from within
"_o159 next addr_"
	("eval" body line 1)
	invoked from within
"eval $self nxt $args"
	(procedure "_o159" line 18)
	(Agent set line 18)
	invoked from within
"$rtproto set addr_"
	(procedure "Agent/rtProto/LS" line 18)
	(Agent/rtProto/LS init-all line 18)
	invoked from within
"Agent/rtProto/LS init-all"
	("eval" body line 1)
	invoked from within
"eval Agent/rtProto/$proto init-all $rtprotos_($proto)"
	(procedure "_o141" line 5)
	(RouteLogic configure line 5)
	invoked from within
"[$self get-routelogic] configure"
	(procedure "_o4" line 4)
	(Simulator run line 4)
	invoked from within
"$ns run
"
	(file "simple-eqp1.tcl" line 142)

***end***

the line 142 referenced is just the command "$ns run" btw.

Cheers,
Mark

Hi,

There is a webpage for that,
http://networks.ecse.rpi.edu/~sunmin/rtProtoLS/

In ns 2.1b7, there is a directory, linkstate,
in which there are files rtProtoLS.{h, cc}, ls.{h, cc}, etc
and .tcl file, ns-rtProtoLS.tcl

I do not have 2.1b7 so not tell you the exact path.
Sure you could find them.
