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 SwiftDNS

, 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
