[j-nsp] traceroute w.x.y.z gateway a.b.c.d

[Chuck Anderson]

I'm trying to test various routes to the same destination, and I'd 
like to do a traceroute using different outbound links.  However, when 
I use "traceroute w.x.y.z gateway a.b.c.d" JunOS apparently adds 
source routing options to the IP packets, and the packets get dropped 
with !S since most ISP's don't allow source routed IP packets:

3  unknown.Level3.net (63.211.178.137)  3.441 ms !S *  3.357 ms !S

Is there any to just override the first routing decision without 
adding source route options?

Thanks.
