Yes, we've been using the ip sla feature for some time now, works well. Bgp/ ospf via quagga also are great solutions . <br><br>Dan Durrer<br><a target="_blank" href="http://No-ip.com">No-ip.com</a><br><br>Sent from my iPad<br><br>On Apr 5, 2010, at 8:39 AM, Matthew Pounsett <<a ymailto="mailto:matt@conundrum.com" href="mailto:matt@conundrum.com">matt@conundrum.com</a>> wrote:<br><br>> <br>> On 2010/04/05, at 02:06, sasa sasa wrote:<br>> <br>>> Hello everyone,<br>>> <br>>> Any one used any load balancer for DNSs? any recommendation? it's 2 caching-only DNSs, and I'd like to make a load balance between them using software.<br>> <br>> Unless you're willing to spend a lot of money, load balancers are generally not the best way to go. They tend to be specced out for "average" internet traffic, which has a much lower packets/megabit ratio than DNS traffic does. You're much better off using routing
protocols to balance traffic between DNS servers.<br>> <br>> Have a look at this[1] how-to .. it'll point you to a technote by ISC about how to do OSPF anycast within a LAN, as well as explain a slightly simpler (but Cisco-only) solution.<br>> <br>> Cheers,<br>> Matt<br>> <br><span>> [1] <<a target="_blank" href="http://mpounsett.blogspot.com/2009/02/load-balancing-dns-using-ciscos-ip-sla.html">http://mpounsett.blogspot.com/2009/02/load-balancing-dns-using-ciscos-ip-sla.html</a>></span><br>> <br>> _______________________________________________<br>> bind-users mailing list<br>> <a ymailto="mailto:bind-users@lists.isc.org" href="mailto:bind-users@lists.isc.org">bind-users@lists.isc.org</a><br>> <a href="https://lists.isc.org/mailman/listinfo/bind-users" target="_blank">https://lists.isc.org/mailman/listinfo/bind-users</a><br></div></div><div style="position:fixed"></div>
