Problems solved by technology

If a malicious attacker constructs and sends a large amount of network traffic with the above destination addresses in the intermediate network spanned by the GRE tunnel, it will seriously consume the network bandwidth resources between the networks spanned by the tunnel and affect the stability and security of the GRE tunnel sex

Embodiment Construction

[0046] The core idea of ​​the present invention is to notify the IP address of the tunnel interface at the opposite end through one end of the GRE tunnel, and assign the IP address of the tunnel interface to the opposite end, so that both ends of the tunnel can perceive the IP address configuration of the tunnel interface of each other In this way, fine-grained host routes can be generated at both ends of the tunnel, thereby avoiding routing loops in the GRE tunnel and improving the flexibility of GRE tunnel configuration and application. The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0047] Please refer to figure 2 , the configuration method of the GRE tunnel described in this embodiment includes the following steps:

[0048] Step 21, the second router configures the source end and the destination end of the GRE tunnel as itself and the first router respectively, and configures the IP addre...

Abstract

The invention provides a GRE tunnel collocation method and a router thereof. An IP address is collocated for the other end by one end of a tunnel, and a fine main router is generated at the two ends of the tunnel in the invention, thus avoiding the problem of routing loop in GRE tunnel and improving the flexibility of GRE tunnel collocation.

Description

technical field [0001] The invention relates to the technical field of Generic Routing Encapsulation (GRE, Generic Routing Encapsulation) in the technical field of data communication, in particular to a configuration method of a GRE tunnel and a router. Background technique [0002] The GRE protocol is used to encapsulate packets of certain network layer protocols (such as Internet Protocol IP and packet exchange protocol IPX), so that these encapsulated packets can be transmitted in another network layer protocol (such as IP). The GRE protocol is the third-layer (network layer) tunneling protocol of a virtual private network (VPN, Virtual Private Network). A technology called a tunnel is adopted between protocol layers. A tunnel is a virtual point-to-point connection. In practice, it can be regarded as a virtual interface that supports point-to-point connections. This interface provides a path through which encapsulated packets can be transmitted. The text is encapsulated ...
