Re: [pacnog] Multihoming Problem





Hello,

Looking at one of our our BGP routers (AS36149) I see you through AS25625.  Have you tried mirroring the traffic to see what it is and where it's going?  Perhaps you could remove proprietary parts of your config and let us see it?

I seem to be having some problems with my multihoming arrangement. Our
current setup is to advertise our /20 on both of our upstream providers:
AS25625 is the primary and AS30362 is the secondary.

I have a 10x as-path prepend for AS30362 since we only have a single T1
with that upstream. There is no as-path prepend on our primary.

What I'm trying to do is have all traffic flow through our primary and
only go through the secondary when the primary link fails. What actually
happens is that our secondary link becomes saturated and our primary
link only runs at about 50% capacity even with the maximum as-path
prepend.

I've checked several looking glass routers and our primary link seems to
be the best path, but I can't account for such a large amount of traffic
on our secondary.

Any suggestions?

P.S. We are AS23657
