The ping generator generates traffic in an IPSec VPN tunnel to keep the tunnel
connection open when no traffic is being generated inside the tunnel. For example,
the ping generator is useful in scenarios where a dialup client or dynamic DNS peer
connects from an IP address that changes periodically—traffic may be suspended
while the IP address changes. You may also use the ping generator to troubleshoot
network connectivity inside a VPN tunnel.
You can configure settings to generate ping commands through two tunnels
simultaneously. The ping interval is fixed at 40 seconds.
The source and destination IP addresses refer to the source and destination
addresses of IP packets that are to be transported through the VPN tunnel. When
source and destination addresses of 0.0.0.0 are entered, no ping traffic is
generated between the source and destination.
To configure the ping generator
1 Go to VPN > IPSEC > Ping Generator.

spoke configuration.
