The following four IPsec parameters configure the rekeying event.
set security ipsec tunnels name "123" IKE-mode
ipsec-soft-mbytes (1000) {1-1000000}
set security ipsec tunnels name "123" IKE-mode
ipsec-soft-seconds (82800) {60-1000000}
set security ipsec tunnels name "123" IKE-mode
ipsec-hard-mbytes (1200) {1-1000000}
set security ipsec tunnels name "123" IKE-mode
ipsec-hard-seconds (86400) {60-1000000}
• The soft parameters designate when the system negotiates a new key. For example,
after 82800 seconds (23 hours) or 1 Gbyte has been transferred (whichever comes
first) the key will be renegotiated.
• The hard parameters indicate that the renegotiation must be complete or the tunnel will
be disabled. For example, 86400 seconds (24 hours) means that the renegotiation
must be complete within one day.
Both ends of the tunnel set parameters, and typically they will be the same. If they are not
the same, the rekey event will happen when the longest time period expires or when the
largest amount of data has been sent.
