CSS configuration with keepalive named set an IP address to the global keepalive.
Into the Cisco document we can read
"Configuring a Global Keepalive IP Address
The CSS sends global keepalives to a service that monitors the state of services assigned to it. Use the ip address command to specify the IP address where the keepalive messages are sent."
This means that we need a dedicated external service to monitor the real services?!
