is there any problem or anything must be taken care about when anycast is employed within a DNS server farm within MAN?
What I mean is, if we want to employ anycast in a cache server farm which is located within a big OSPF network, is there anything problemetic ? or should we consider anycast only when root server is to be installed ?
Since OSPF generally converges orders of magnitude faster and it's easier to get OSPF to select the highest bandwidth/lowest latency path than BGP, this should be easier.
Also, be mindful of ECMP. http://www.isc.org/pubs/tn/isc-tn-2004-1.html http://www.isc.org/pubs/tn/isc-tn-2004-1.txt Joe
