IP Anycasting

The animated TECHTip Tutorial is available here.

IP Anycast is defined, by Cisco, as the point-to-point flow of IP [Internet Protocol] packets between a single client and the “nearest” destination server identified by any IP Anycast address.

Criteria for selecting “nearest” server determines the type of anycast content, also referred to a Virtual IP address with mirrored (duplicated or load-balanced disk) servers sharing same IP address. That is, the DNS [Domain Name Server] maps (identifies) unique IP address which then distributes content to local or remote content servers.
