Table 4-2-8-3 IPsec Parameters
4.2.8.3 GRE
Generic Routing Encapsulation (GRE) is a protocol that encapsulates packets in order to route other
protocols over IP networks. It’s a tunneling technology that provides a channel through which
encapsulated data message could be transmitted and encapsulation and decapsulation could be realized
at both ends.
In the following circumstances the GRE tunnel transmission can be applied:
- GRE tunnel could transmit multicast data packets as if it were a true network interface. Single use of
IPSec cannot achieve the encryption of multicast.
- A certain protocol adopted cannot be routed.
- A network of different IP addresses shall be required to connect other two similar networks.
