[ns] Question about the DSR agent: piggybacketed Route Error message on Route Request message?

[Liang Qin <lqin@sce.carleton.ca>]

Hi ns-users,

I'm reading ns2 (2.1b6) DSR agent code (dsragent.cc). When a node sends a Route
Requst message, it will piggyback a Route Error with it (if any, method
sendOutRtReq( ) ). But I didn't find any procedure in handleRouteRequest( )
which will check the Route Error message (if any).

Could anyone please explain the reason why not implementing it?

Thanks a lot.
