[AusNOG] BGP query

[Alex Samad - Yieldbroker]

Hi

I noticed something strange on the weekend with my BGP setup. Thought I would ask the group if it looks strange to. 

So at work we peer with Internode and Pipe.  My home connection is with TPG.
I noticed on the weekend my traffic was routing asymmetrically 

My home -> TPG -> Work
Work -> Internode -> My home

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


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.

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.

I did contact the NOC @ Pipe.. As far as they are concerned every things okay.  Let me paraphrase... 1 company 2 businesses 


I am not sure why TPG would want to do that ?
