Hash-Key - GTP Tunnel-id - IPv4/v6

This feature introduces load balancing of IPv4 or IPv6 packets by using GPRS Tunneling Protocol-tunnel endpoint identifier (GTP-TEID) field hash calculations. The GTP-TEID hashing is used together with Layer 3 fields hashing. GTP versions 1 and 2 are supported for hashing user data only. Juniper does not recommend enabling this option by default. This is because GTP session identification is based on the destination UDP port match (2152), and this port may not be exclusively used for GTP transport, so the extraction of the GTP-TEID field from the packet may not always be accurate.
