5.2 Load Balancing With multiple Internet connections, Load Balancing effectively uses the combined
bandwidth of all the internet l inks resulting in a significant increase in the total available
bandwidth. Also if any Internet connection goes down, uninterrupted internet
connectivity is assured utilizing the serviceable links.
Based on the speed of the WAN link, the administrator can configure an appropriate
percentage of internet traffic to be routed through each of the WAN Links.
Note: The priority of route lookups is in the following order:
a) Policy Based Routing (PBR) routes
b) Static/Dynamic routes
c) Load Balancing routes
Select Interface →

→ LoadBalancing to configure the Load Balancing Configuration as
explained below.
Load Balancing Configuration
Load Balancing Select to enable the load-balancing feature.
Interface WAN interfaces between which the load must be shared.
Status Enable/Disable load-balancing on this interface.
Weight Percentage of the load to be sent through this interface. The sum of the
weights in all enabled interfaces should be equal to 100.
Caution: Load Balancing feature will not function as desired if default routes are
added via Static Routing, since static routes will be given higher preference.
In case of Ethernet WAN Connectivity (Static and Dynamic Modes) there is no specific
control protocol to detect the link status. Ethernet WAN Link Detection Feature in the
router enables you to detect link failures through periodic transmission of ICMP/ARP
messages.
Note: When using Static/Dynamic mode of WAN Interfaces, it is imperative to enable
Ethernet Link Detection for proper functionality of Load Balancing and Auto Backup
features.
