My vendor complains that, because he doesnt send traffic before the (24 hour) tunnel timeout expires, the tunnel keeps closing, and when his software tries to then send a query over the tunnel, it fails.
Security dictates that we cannot keep the tunnel perpetually open.
Thus, needed is a keepalive config-- I expect it is some SLA config that pings the remote interface perpetually. Will the remote vendor device also need configuration? Will BGP need to be involved?
Can you please tell me the logical solution here, and please send some kind of config reference link?
