Josh,
     ICMP Redirect's are error messages informing you that you
are using the wrong default router...and should be using one at
a different address.  If your system "replies" to ICMP Redirects
that reply will itself generate another ICMP message.  Invoking
a kind of death spiral, as the ICMP's flood the link and use all
the bandwidth it is capable of.  Each packet sent to the wrong
router will generate an ICMP Redirect message!  That message is
trying to inform your system that you should use the router at
IP address xxxxxxx instead; it probably has a better path, or
whatever.  If your system does not adapt to and use the router
the message is asking you (telling) the redirects will continue
and one will be returned for each and every packet trying to use
the wrong one!
