Load balancing between two gateways

Load balancing between two gateways
For load balancing between two gateways use:
ip route del default ip route add default scope global nexthop via <gateway_1> dev <interface of gateway 1> weight 1 \ nexthop via <gateway_2> dev <interface of gateway 2> weight 1
Here weights can be changed to make one route more preferable to other.
We can use 'ip route show' command to verify that routes got added properly.
