<p class=MsoNormal>Hi All,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Does anyone know any techniqiues or ways to block BGP
adverts to third party AS’s, or a similar method for dropping routes *<b>to</b>*
our AS from a distant, non directly connected AS ?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>For example, is there a way to inject or craft maybe a
network unreachable message or something that we can send to the offending A.S.
to remove their routing information for *<b>our</b>* network / AS / IP ranges?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My scenario is that I’m trying to block UDP floods to
our network, and I’m sure many of you have had experience with this. Im
not looking for a total solution, although If you have any recommendations ,
that would be great. What I’m really after is just once peice of the
puzzle to see if we can selectively choose which remote networks we are visible,
as a direct first step to stopping attacks until a human can intervene.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Cheers,<o:p></o:p></p>
<p class=MsoNormal>Sean.<o:p></o:p></p>
