Configuring Weighted Load Balancing for LAC Tunnel Sessions
You can configure how L2TP LAC sessions are distributed across tunnels. You can specify that the router uses the maximum sessions per tunnel to choose among multiple tunnels that share the same preference level.
The weight of a tunnel is proportional to its maximum session limit and the maximum session limits of the other tunnels at the same preference level. The tunnel with the largest maximum session value has the highest weight. The tunnel with the next larger maximum session value has the next higher weight, and so on. The tunnel with the smallest maximum session value has the lowest weight.
When you configure weighted load balancing, the tunnel with the highest weight in the preference level is selected until the maximum number of sessions for the tunnel is reached. Then the router selects the tunnel with the next higher weight to establish connections until that tunnel’s maximum session limit is reached, and so on.
To configure weighted load balancing:
