I found the following useful: http://www.net.cmu.edu/pres/anycast http://ftp.isc.org/isc/pubs/tn/isc-tn-2004-1.html http://www.linuxsa.org.au/meetings/2006-07/anycast-dns.pdf They're getting a bit dated, but still OK. ________________________________________________________________________ Jay Ford, Network Engineering Group, Information Technology Services University of Iowa, Iowa City, IA 52242 email: jay-ford@uiowa.edu, phone: 319-335-5555, fax: 319-335-2951

If you're interested in looking at it from a campus/enterprise point of view, we recently reworked our DNS/Anycast setup, and here are the deployment notes: http://www.contrib.andrew.cmu.edu/~somlo/DNS.html (you can stop reading at section 4, where it gets into the specifics of our homebrew IPAM system). In a nutshell, we're using the "ip sla" feature on our Cisco boxes to conditionally announce host routes for the published anycast IPs from several places in our network (subsection 2.4 in the document).
