Description
For better distribution in load balancing for L2TP tunneled traffic, enable
l2tp-tunnel-session-identifier to have the hash calculation of
IPv4 or IPv6 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.
