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 the hosts, which send packets
to the tunnel that the tunnel is down. It does so, even though the source interface continues to
send keepalive packets.
