keepalive (GRE tunnel)

Use the keepalive command in the context of a GRE tunnel to specify that the tunnel sends
keepalive packets to determine if the tunnel endpoint is up. Packets are sent according to the
interval specified in the seconds parameters, and resent according to the number of the retries
parameter.
Use the no form of the command to disable keepalive packets.
If the tunnel's destination interface fails to respond to a consecutive number of keepalive
packets equal to the <retries> parameter, the tunnel informs hosts that send packets to the
tunnel that the tunnel is down, although the source interface continues to send keepalive
packets.
