Hello,
I have setup anycast DNS using BIND as the DNS server and BIRD
routing daemon. I have 1 route server
and 5 route clients.
If you are using anycast, why not just let the routers load multiple
routes to the destination IP, and let it do 'load balancing', rather
than adding another layer of complexity?
Not sure how you do that with BIRD, but you can use the
'maximum-paths' option on a Cisco router to allow more than one BGP
route to a particular destination subnet to end up in the routing table.
Yes, the route server has the multiple routes to the destination IP and
it will peer at IX. The route clients are distributed geographically.
I want to provide another layer of load balancing (and failover) within
a route client at each location.
Such that a request doesnt get routed all the way to another location
because just one server at the route client is down.
