IP Tunnel GRE Settings
This window is used to configure an existing tunnel as a GRE tunnel (IPv6/IPv4-in-IPv4 or IPv6/IPv4-in-IPv6) on the
Switch. If this tunnel has been configured in another mode before, the tunnel's information will still exist in the
database. However, whether the tunnel's former information is valid or not, it depends on the current mode.
GRE tunnels are simple point-to-point tunnels that can be used within a site or between sites.
When a user wants to configure a GRE IPv6/IPv4-in-IPv4 tunnel, both the source and destination address must be
IPv4 addresses because the delivery protocol is the IPv4 protocol. If the source and destination address type are
not consistent, then the GRE tunnel will not work.
When a user wants to configure a GRE IPv6/IPv4-in-IPv6 tunnel, both the source and destination address must be
IPv6 addresses because the delivery protocol is the IPv6 protocol. If the source and destination address type are
not consistent then the GRE tunnel will not work.
