11.3 GRE
This section allows you to set GRE configuration. The default mode is off.
Generic Routing Encapsulation (GRE) is one of the available tunneling mechanisms which uses
IP as the transport protocol and can be used for carrying many different passenger protocols. The
tunnels behave as virtual point-to-point links that have two endpoints identified by the tunnel source
and tunnel destination addresses at each endpoint.
 GRE Tunnel interface comes up as soon as it is configured.
 Local endpoint does not bring the interface down if the remote endpoint is unreachable.
 No way to determine problems in the intervening network.
 Keepalives are used to solve this issue.
The GRE Tunnel Keepalive feature provides the capability of configuring keepalive packets to be
sent over IP-encapsulated GRE tunnels. You can specify the rate at which keepalives will be sent
and the number of times that a device will continue to send keepalive packets without a response
before the interface becomes inactive. GRE keepalive packets may be sent from both sides of a
tunnel or from just one side.
