The necessary prerequisites for configuring Anycast BGP.
- BGP hardware and network setup—Autonomous Systems containing a BGP peer are properly setup and configured; DNS Servers have been properly setup and configured with necessary IPv4 and IPv6 addresses.
- DNS/DHCP Servers under Address Manager control—all DNS Servers
that will be part of Anycast BGP must first individually added and managed by Address Manager.Note:
- Dedicated management is supported with Anycast BGP.
- IPv4/IPv6 addresses configured on the Services interface (eth0) must be on different subnets.
- DNS Service—ensure you have created views, zones, deployment
roles, and resource records, required for your Anycast BGP network and have deployed DNS
service to your DNS Servers. DNS data on the slave DNS Server may not be populated until
the entire Anycast BGP network is operational.Attention: Autonomous System Numbers
Anycast BGP requires an Autonomous System Number (ASN) allocated for each Autonomous System in the Anycast BGP network. Any ASNs used in the Internet must be officially registered and allocated by the Internet Assigned Numbers Authority (IANA). If ASNs are only used within a corporate network and the corresponding AS has no direct connection to the Internet, then ASNs may be chosen freely from within the range reserved for private use: 64512-65534.
