16.6 Keep Alive
When you initiate an IPSec tunnel with keep alive enabled, the Prestige automatically renegotiates the
tunnel when the IPSec SA lifetime period expires (see Section 16.11 for more on the IPSec SA lifetime). In
effect, the IPSec tunnel becomes an “always on” connection after you initiate it. Both IPSec routers must
have a Prestige-compatible keep alive feature enabled in order for this feature to work.
