Soft GRE Profile

Overview

Before configuring soft GRE tunnel forwarding, configure a soft GRE profile first so that data packets can be forwarded according to parameters configured in the profile.

In a soft GRE profile, the destination address of the soft GRE tunnel must be configured to specify the destination to which service data is forwarded.
A soft GRE tunnel is not capable of detecting tunnel status. If the remote interface is unreachable, the soft GRE tunnel cannot be immediately tore down. As a result, the source end continues sending data to the remote end, wasting device resources and bandwidth of the intermediate network.

The Keepalive detection function can monitor the soft GRE tunnel status to check whether the remote end is reachable. If the remote end is unreachable, the source end tears down the tunnel immediately to reduce resource waste and bandwidth occupation.
