Re: Cisco Traceroute and UDP src port range.

Thanks for the Link Scott!
I am asking this question form the perspective of LAB exam where, If asked
to configure an ACL (Somewhere in the path), but still allow outgoing
traceroute Packets.
I know the UDP port range starts form 33434, but I am clueless about the
upper limit. :(
