You can set up the router software to clear IKE SAs automatically when the corresponding services PIC restarts or is taken offline. To configure this property, include the clear-ike-sas-on-pic-restart statement at the [edit services ipsec-vpn] hierarchy level:
-
clear-ike-sas-on-pic-restart;
After you add this statement to the configuration, all the IKE SAs corresponding to the tunnels in the PIC will be cleared when the PIC restarts or goes offline.
