MA5800 GRE Hardware Processing

Hi user!

Generic Routing Encapsulation (GRE) is a protocol that encapsulates packets of some network layer protocols, such as Internetwork Packet Exchange (IPX), IPv6, and AppleTalk. Then the encapsulated packets can be transmitted over a different network layer protocol, such as IPv4.

As Layer 3 tunneling technology, GRE encapsulates packets of a protocol into packets of another protocol to transparently transmit packets over GRE tunnels. This technology enables packet transmission on heterogeneous networks.

Hello, friend!

The software is responsible for protocol and negotiation, generates paths, and delivers the paths to the hardware. The hardware is responsible for forwarding.
