HE.net and BGP Communities

Mon Jul 25 11:21:04 UTC 2022

You always want to prefer customer routes over non customer routes as a service provider. Of course having a robust set of communities to let adjustments happen helps. 

Without proper tiering of routes you may see unstable routing. 

Having a standard set of customer, peer, transit set of local preferences would go a long way. Same for geographic scope of routes, only use these on same continent. Makes using a provider if you do something like anycast hard if they haul you long distance.
