    Hi,

    Todd MacDermid has written two excellent tools for LSRR testing, titled
    lsrscan and lsrtunnel, and available from http://www.synacklabs.net. You
    can use lsrscan to test individual routers, firewalls, servers, etc., and
    see if they process LSRR packets, and if they reverse the specified route
    too.

    For examples of lsrscan and lsrtunnel, along with some nice figures, see
    pages 61-64 of the Chapter 4 PDF from Network Security Assessment, at
    http://www.oreilly.com/catalog/networksa/chapter/ch04.pdf

    Take it easy,

    Chris
