Route Server Filters at IXPs and 4-byte ASNs

Sat Jan 25 15:04:30 UTC 2014

I have over 100,000 servers located in routing diverse datacenters with
4byte ASN numbers and have not had 1 problem or complaint related to the
ASN for not able to communicate with the datacenter.  The first 1 did make
me really nervous for all of the reasons already mentioned but turned out
to be a non-issue.

While it would be nice to see community string support increase to 4byte, I
think this is more of an educational challenge for the IXPs on how to setup
your community strings to work and not really a technical problem.
