IP Tunneling

  • Sharding support for dynamic IP-over-IP tunneling (PTX10001-36MR, PTX10003, PTX10004, PTX10008, and PTX10016)—Starting in Junos OS Evolved Release 22.2R1, we support sharding for dynamic tunnels created as a result of BGP route resolution over a tunnel route. The protocol uses this tunnel route as a helper route for route resolution.

  • L2TPv3 header for load balancing (PTX10001-36MR, PTX10004, PTX10008, and PTX10016)—Starting in Junos OS Evolved Release 22.2R1, the device takes Layer 2 Tunneling Protocol version 3 (L2TPv3) header attributes into account when load balancing. When L2TPv3 packets are encapsulated in IP tunnels, the device identifies L2TPv3 packets by the IP protocol type 115. The session ID of the L2TPv3 packet headers distinguishes the traffic flows in L2TPv3-over-IP tunnels. The device uses the session ID of L2TPv3 packets in the hash computations to better manage traffic flows during load balancing.

    L2TPv3-based load balancing is enabled by default. To disable this feature, use the no-tunnel-payload statement at the [edit enhanced-hash-key family any] hierarchy.
