Abstract

The invention discloses a method and a device for controlling the interface state of routing equipment. The invention has the main technical scheme that the method comprises the following steps: carrying out route selection on channel target addresses configured by a first routing equipment interface corresponding to the current channel to determine a second routing equipment interface used for carrying the channel; updating the counter value corresponding to the first routing equipment interface according to the counter valve corresponding to the second routing equipment interface; and configuring the first routing equipment interface into a non-working state when the counter valve corresponding to the first routing equipment interface is determined to reach the set threshold value. According to the technical scheme, the multiple nested encapsulation of messages can be avoided at the source, and the operation efficiency of the routing equipment can be improved. In addition, the generation of the unlimited recursion nested channel can be effectively prevented, and the channel nesting can be realized in channels such as IPv4 over IPv4, IPv6 over IPv4, IPv4 over IPv6 and the like including the IPv4 protocols.

Description

technical field

[0001] The invention relates to the technical field of tunnels, in particular to a method and device for controlling the state of an interface of a routing device. Background technique

[0002] Tunnel technology is an encapsulation technology that enables IPv6 networks to communicate with each other in IPv4 networks. It uses one network protocol to transmit another network protocol, that is, a network protocol encapsulates data packets generated by other protocols in its own In the message, and then transmitted in the network. A tunnel (Tunnel) is a virtual point-to-point connection that provides a transmission path for encapsulated data packets, and the data packets need to be encapsulated and decapsulated at both ends of the tunnel. Tunnel technology refers to the whole process including data encapsulation, transmission and decapsulation.
