VPN force-all
GRE tunnelling suppor ts “VPN force-all,” which forces all traffic coming from the LAN onto the GRE tunnel. You
accomplish this by setting the default route to go through the GRE tunnel. A secondar y host route where all
tunneled GRE packets route to the actual WAN inter face can be configured as a static route when required.
The following table outlines various force-all configurations for different networking scenarios; all other options
can safely use their default values:

Note: A GRE tunnel cannot transmit RIP routes over a force-all tunnel, or with a remote member IP with a
host par t of all zeros.
