3.4Alternate Border Controllers

Alternate Border Controller support is provided to increase the reliability of your deployment. If one Border Controller becomes unavailable, perhaps due to a network or power outage, another will be used as an Alternate. Alternates share responsibility for their endpoint community: an individual endpoint may be registered with any one of the Alternates. You should configure Alternates identically for all registration and call features such as authentication, bandwidth control and policy. If you do not do this, endpoint behavior will vary unpredictably depending on which Alternate it is currently registered with. Alternates should also be deployed on the same LAN as each other so that they may be configured with the same routing information such as local domain names and local domain subnet masks.

Each Border Controller may be configured with the IP addresses of up to five Alternates. When an endpoint registers with the Border Controller, it is presented with the IP addresses of all the Alternates. If the endpoint loses contact with its initial Border Controller, it will seek to register with one of the Alternates. This may result in your endpoint community’s registrations being spread over all the Alternates.

Enterprise Gatekeepers which register with the Border Controller may also be given a list of Alternate Border Controllers to use.

When a Border Controller receives a Location Request, if it cannot respond from its own registration database, it will query all of its Alternates before responding. This allows the pool of registrations to be treated as if they were registered with a single Border Controller.

The Alternate Border Controllers can be configured within the web interface of the Border Controller by navigating to Border Controller Configuration → Gatekeeper. Up to five different alternates can be configured. Please see Figure 2 for a screenshot of a sample configuration.
