Internet Key Exchange (IKE) Settings
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 begins to negotiate a new key. For example, after
82800 seconds (23 hours) or 1 Gbyte has been transferred (whichever comes first) the key will begin to
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.
