has someone experience in anycast ipv4 networks (to support DNS)?
"Never been done" "Dangerous" "TCP does not work" etc etc etc.
- Yes but as for DNS, anycast is essentially used for user requests (UDP) not to perform zone transfer(TCP).
How-to with working configurations for Linux+Quagga: <www.linuxsa.org.au/meetings/2006-07/anycast-dns.odt> Further information is found in RFC3258: <http://tools.ietf.org/html/rfc3258> Remember to disable PMTU discovery on your DNS servers if you are using this. Paul
