Tunnel interface view
Default command level
2: System level
Parameters
seconds: Specifies the interval in seconds for transmitting keepalive packets, in the range of 1 to 32767.
The default value is 10.
times: Specifies the maximum number of attempts for transmitting a keepalive packet, in the range of 1
to 255. The default value is 3.
Usage guidelines
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
sending the keepalive packet for the maximum number of attempts, the local tunnel interface goes down
and stays down until it receives a keepalive acknowledgement packet from the peer.
Examples
# Set the GRE keepalive interval to 20 seconds and the maximum number of transmission attempts to 5.
