The headquarters is a fixed IP, the branches have ADSL and fixed IP, and the branches establish IPSec with the headquarters; L2L VPN: every time a branch triggers the establishment of a VPN, because there is no data transmission, the VPN tunnel will be down after a while. The lifetime of ISAKMP and IPSec will be changed to 10 days, but it will be down after a period of time. No matter how much the lifetime is, it will be down automatically if it is idle? How can we not let it down automatically?
