Configuring Anycast

Anycast configuration incorporates the following common parameters shared by all hosts in support of a particular service.

• An anycast configuration can incorporate multiple hosts while a host may be a member of multiple anycast configurations.
• All hosts in an anycast configuration must belong to the same tenant that owns the anycast configuration.
• All anycast addresses configured for a particular host will be advertised to the same set of upstream routers.

Depending on your license entitlement, you can associate an anycast address with multiple hosts that are serving the same Infoblox Platform. Note that each anycast address must be unique for a specific protocol. For example, if you have the Infoblox Threat Defense Advanced license entitlement, you can create an anycast address and associate it with multiple hosts that have DNS forwarding proxy service enabled and running on them. Similarly, if you have the Universal DDI Advanced entitlement, you can associate one anycast address with multiple hosts that are serving DNS.

To set up anycast addressing, do the following:

1. Create an anycast configuration, as described in Creating Anycast Configuration.
2. Create an anycast service instance, as described in Creating Anycast Services.
3. For Anycast 2.0, configure the desired anycast protocol as described in Configuring Routing.

The Configure > Networking > Anycast page displays the following information about the Anycast configurations currently in your system.

• NAME: The anycast configuration’s name.
• ANYCAST IPv4 ADDRESS: The IPv4 address used by the anycast configuration.
• ANYCAST IPv6 ADDRESS: The IPv4 address used by the anycast configuration.
• DESCRIPTION: Description of the name of the host.
• STATE: The current state of the anycast configuration. This can be one of the following:
  • Active: The anycast service is enabled and running properly on all configured hosts.
  • Inactive: The state is Inactive if any of the following happens:
    • The anycast service is disabled.
    • The anycast service is enabled, but no anycast service is running on the configured hosts.
  • Degraded: The anycast service is not running properly on one or more of the configured hosts.
• SERVICE TYPE: The service for which you configure anycast.

You can view more information about a selected anycast configuration in the right panel. When you expand Anycast Services in the panel, you can see the current state of the anycast service for each configured  host.
