[ns] Attaching routing agent to nodes

[Erik Kline]

Dear NS-users,

I have created a new routing protocol that is almost completely in
C++.  The routing protocol is designed for WIRED routing and has all
the basic properties (recv, command, forward_data, etc...).  The
problem I'm having is trying to determine how to attach my routing
agent to my nodes.  I can attach the agent using:

$node attach-agent [new Agent/Proto ...] 255

but when I build applications and agents, they do not use my routing
agent to route packets.  (Probably still using default static
routing).  So, I'm trying to figure out what TCL code I need to add to
make it such that my routing agent becomes the routing agent for the
nodes.

I have also tried adding TCL extensions similar to that of DV but I
continuously get errors.  For example, after telling the rtObject to
add my protocol, I want to run a few protocol commands.  I have set me
protocol to an object rtproto but when I run the command:

$rtproto cmd <command-name> <args>

I get an error even though the error message is unclear, something like this:

 (_o46 cmd line 1)
    invoked from within
"$rtproto cmd address [$node node-addr]"

even though I'm 100% sure the command I ask for is excepted in my
command function.  Any help would be appreciated.
