These devices can load-balance packets based on the tunnel they belong to. When Layer 2 Tunneling Protocol version 3 (L2TPv3) packets are encapsulated in IP tunnels, the packet header includes a tunnel ID and a session ID that distinguishes the traffic flow that packet belongs to. The device uses this information in the L2TPv3 packet headers when performing the hash computations for load balancing. This feature enables the device to better manage traffic flows in L2TPv3-over-IP tunnels.
To enable and disable L2TPv3-header based load balancing, use the l2tp-tunnel-session-identifier statement at the [edit enhanced-hash-key family family] hierarchy, where the family can be inet or inet6.
