Use the
undo keepalive
By default, the GRE keepalive function is disabled.
With the GRE keepalive function enabled on a tunnel interface, the device sends
GRE keepalive packets from the tunnel interface periodically. If no response is
received from the peer within the specified interval, the device retransmits a
keepalive packet. If the device still receives no response from the peer after a
keepalive packet is transmitted for the maximum number of attempts, the local
tunnel interface goes down and keeps down until it receives a keepalive
acknowledgement packet from the peer.
