<div>TPG want to influence traffic to traverse via Transit links
which are more expensive than via Peering exchanges (even there
own).</div>

</div>
<div>It's a silly network strategy and only hurts there own
customers but at the same time increases the amount of bandwidth
required by PIPE Transit customers which equals more revenue :(</div>

<div>PS I love path stuffing but the term technically is path

<div><span>Hi</span><br>
<span></span><br>
<span>I noticed something strange on the weekend with my BGP
setup. Thought I would ask the group if it looks strange to.
</span><br>
<span></span><br>
<span>So at work we peer with Internode and Pipe. My home
connection is with TPG.</span><br>
<span>I noticed on the weekend my traffic was routing
asymmetrically </span><br>
<span></span><br>
<span>My home -> TPG -> Work</span><br>
<span>Work -> Internode -> My home</span><br>
<span></span><br>
<span>Found this rather strange as I thought PIPE -> TPG
would be the preferred path. So I dug into my BGP peers and
looked at the tables</span><br>
<span></span><br>
<span></span><br>
<span>What I found was rather strange from internode I had this
AS path 4739,18398,7545, from Pipe I have this AS path
24130,7545,7545,7545, so for some reason TPG is AS stuffing (?
Right term ? ) their prefix to Pipe.</span><br>
<span></span><br>
<span>That's rather strange I think. I don't want to have to
mess too much with my BGP filters to do to any trick things, I
believe I would re weight it such that TPG via pipe is the
preference, but I wonder why TPG would do this.</span><br>
<span></span><br>
<span>I did contact the NOC @ Pipe.. As far as they are
concerned every things okay. Let me paraphrase... 1 company 2
businesses
</span><br>
<span></span><br>
<span></span><br>
<span>I am not sure why TPG would want to do that ?</span><br>
<span></span><br>
