I have a client with data centres all around the world.  They have a public AS number from pretty much every registry.

Lets consider a smaller part of the picture, just Asia Pacific.  They use maybe 6 data centres in the APNIC area, all using the one public ASN from APNIC.  The data centres do not have a common carrier/connectivity between them.  A couple of sites are connected via VPN, 2 or 3 are connected with one carrier and the others with a different carrier again.  Most sites have more than one link to other sites for redundancy.  All links are either layer 2, or point to point layer 3.  Most sites have 3 or 4 BPG devices in them, all in the same AS.

Creating a full iBGP mesh within a singe data centre is ok.  But I have had to use a lot of route reflectors to build the connectivity between the different data centres.

I have never used a BGP Confederation before, but I am starting to think this will be the most manageable way.  Make each datacentre a a separate sub-AS, because I can easily create a full mesh within a data centre.  Then peering between the sub-AS's will become trivial, while still providing the appearance of a single AS to all the external peers.

Have you use BGP Confederation before?  Had a good/bad experience?

You might have better luck asking this on NZNOG?






Information wants to be free. The Net interprets censorship as damage and routes around it.

I wouldn't bother with Confederations.

How many BGP speakers are you talking about? If you only have 3 or 4 devices per sites it should be quite doable with using Route Reflectors.

Worth looking at the Virtual RR's now which alot of vendors are coming out with. Memory is no longer a big issue with those.
