Description
For better distribution in load balancing for L2TP tunneled traffic, enable l2tp-tunnel-session-identifier to have the hash calculation of IPv4 packets include
L2TP header parameters (tunnel ID and session ID). With this option enabled, Junos OS generates
different hashes for packets from different tunnels. It will also generate different hashes
for packets that belong to the same tunnel, but different sessions. L2TP control traffic is
not load balanced based on tunnel ID and session ID.
When the l2tp-tunnel-session-identifier option is not enabled, the same hash
value is computed for L2TP tunneled traffic using the outer IP header, regardless of tunnel
(for tunnels created between the same end points).
To help diagnosis load balancing issues, you can run the request pfe execute command
"show jnh lb" target target command from the Junos OS command line.
