BR-6641’s auto-routing service is a trunking technology that provides load balancing and fault tolerance for all outbound requests. But it does not apply to inbound requests. Based on a unique technology called SwiftDNSTM, BR-6641 offers a Multihoming service for load balancing and fault tolerance for inbound requests. The minimum requirement for Multihoming is that you must have multiple WAN links and registered domain names for your publicly accessible servers. Whenever BR-6641 receives a DNS query; it answers the DNS query with a public IP address assigned to one of the WAN links according to the settings of your answering policies. Therefore, subsequent requests to your server will be sent the public IP of the WAN link based on BR-6641’s previous response. You can configure your answering policies with a weight for each WAN link so that the public IPs returned will be distributed evenly by weight. If one of your WAN links fails, BR-6641 will not return the public IP assigned to that failed link nevertheless your publicly accessible servers
