Generic routing encapsulation - Wikipedia
GRE packets that are encapsulated within IP directly, use IP protocol type 47 in the IPv4 header's Protocol field [3] or the IPv6 header's Next Header field. [4] For performance reasons, GRE can also be encapsulated in UDP packets. [5] Better throughput may be achieved by using Equal-cost multi-path routing.
RFC 2784: Generic Routing Encapsulation (GRE) - RFC Editor
The payload is first encapsulated in a GRE packet. The resulting GRE packet can then be encapsulated in some other protocol and then forwarded. We will call this outer protocol the delivery protocol. The algorithms for processing this packet are discussed later. Finally this specification describes the intersection of GRE currently deployed by ...
GRE报文格式 - IP 报文格式大全 - 华为 - Huawei Technical Support
系统收到需要进行封装和路由的某网络层协议（如IPX）数据时，将首先对其加上GRE（Generic Routing Encapsulation）报文头，使之成为GRE报文，再将其封装在另一协议（如IP）中。
What is GRE tunneling? | How GRE protocol works - Cloudflare
What does GRE tunneling mean? Encapsulating packets within other packets is called "tunneling." GRE tunnels are usually configured between two routers, with each router acting like one end of the tunnel. The routers are set up to send and …
GRE - IP Packet Format - Huawei - Huawei Technical Support
Generic Routing Encapsulation (GRE) encapsulates the packets of certain network layer protocols such as Internetwork Packet Exchange (IPX) packets, and transmits them by using another network layer protocol such as IP.
RFC 1701: Generic Routing Encapsulation (GRE) - RFC Editor
In the most general case, a system has a packet that needs to be encapsulated and routed. We will call this the payload packet. The payload is first encapsulated in a GRE packet, which possibly also includes a route. The resulting GRE packet can then be encapsulated in some other protocol and then forwarded.
Generic Routing Encapsulation (GRE) Tunnel - GeeksforGeeks
2020年8月12日 · GRE packet now travel through path in network defined by various routing protocols and reaches R2’s tunnel interface (tunnel 1). R2 upon receiving the GRE packet, decrypt the packet i.e, removes delivery and GRE header. R2 now forwards the IP packet according to original destination address to the server.
RFC 7637 - NVGRE: Network Virtualization Using Generic Routing ...
The following sections detail the packet format for NVGRE; describe the functions of an NVGRE endpoint; illustrate typical traffic flow both within and across data centers; and discuss address/policy management, and deployment considerations.
GRE format - Nokia
In accordance with RFC 2784, a GRE encapsulated packet has the following format: The delivery header is always an IPv4 header. The GRE header format is shown in Figure: GRE header and described in Table: GRE header descriptions.
What Is GRE? - Huawei Wireless Network Information Center
2024年7月16日 · Generic Routing Encapsulation (GRE) is a tunneling technology that encapsulates data packets of one network protocol with another network protocol, so that the encapsulated packets can be transmitted using the latter network protocol.
