5.6.4. GRE
The Generic Routing Encapsulation (GRE) is a tunneling protocol that can encapsulate
a wide variety of network layer protocols inside virtual point-to-point links over IP. GRE
is defined in RFC 1701, 1702 and 2784. It does not provide encryption nor authorization
but can be used on an address-basis on top of other VPN techniques (such as IPsec) for
tunneling purposes.
The following parameters are required for setting up a tunnel:
Parameter
GRE Configuration
Peer address
The IP address of the remote peer
Interface
The device type for this tunnel
Local tunnel address
The local IP address of the tunnel
Local tunnel netmask
The local subnet mask of the tunnel
Remote network
The remote network address of the tunnel
Remote netmask
The remote subnet mask of the tunnel
In general, the local tunnel address/netmask should not conflict with any other interface
addresses. The remote network/netmask will result in an additional route entry in order
to control which packets should be encapsulated and transferred over the tunnel.
