IPv4 Anycast Resoure Recommendations

I was wondering if anyone had recommendations on IPv4 Anycast resources
(whitepapers, RFCs) as it relates to DNS?

Thanks in advance.

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.

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).

HTH,
