Chapter 18 DNS Inbound LB Table 160 Configuration > Network > DNS Inbound LB > Add/Edit (continued) LABEL DESCRIPTION Zone Load Balancing Member Load Balancing Algorithm Select the zone of DNS query messages upon which to apply this rule. Select a load balancing method to use from the drop-down list box. Select Weighted Round Robin to balance the traffic load between interfaces based on their respective weights. An interface with a larger weight gets more chances to transmit traffic than an interface with a smaller weight. For example, if the weight ratio of wan1 and wan2 interfaces is 2:1, the Zyxel Device chooses wan1 for 2 sessions' traffic and wan2 for every session's traffic in each round of 3 new sessions. Select Least Connection to have the Zyxel Device choose the member interface which is handling the least number of sessions. Select Least Load - Outbound to have the Zyxel Device choose the member interface which is handling the least amount of outgoing traffic. Select Least Load - Inbound to have the Zyxel Device choose the member interface which is handling the least amount of incoming traffic. Failover IP Address Add Edit Remove # IP Address Monitor Interface Weight OK Cancel Select Least Load - Total to have the Zyxel Device choose the member interface which is handling the least amount of outgoing and incoming traffic. Enter an alternate IP address with which the Zyxel Device will respond to a DNS query message when the load balancing algorithm cannot find any available interface. Click this to create a new member interface for this rule. Double-click an entry or select it and click Edit to open a screen where you can modify the entry's settings. To remove an entry, select it and click Remove. The Zyxel Device confirms you want to remove it before doing so. This field displays the order in which the Zyxel Device checks this rule's member interfaces. This field displays the IP address of the member interface. This field displays the name of the member interface. The Zyxel Device manages load balancing between the member interfaces. This field is available if you selected Weighted Round Robin as the load balancing algorithm. This field displays the weight of the member interface. An interface with a larger weight gets more chances to transmit traffic than an interface with a smaller weight. Click OK to save your changes back to the Zyxel Device. Click Cancel to exit this screen without saving. 18.2.2 The DNS Inbound LB Add/Edit Member Screen The Add Load Balancing Member screen allows you to add a member interface for the DNS load balancing rule.
