Connectivity
Check
The interface can regularly check the connection to the gateway you specified to make sure it
is still available. You specify how often the interface checks the connection, how long to wait for
a response before the attempt is a failure, and how many consecutive failures are required
before the SBG stops routing to the gateway. The SBG resumes routing to the gateway the first
time the gateway passes the connectivity check.
