Embodiment Construction

[0051] Aiming at the problems existing in the prior art that cannot meet the high-bandwidth, low-delay business standards of the data center, etc., and will greatly reduce the user experience, the embodiment of the present invention provides a routing management method, which is applied to the first network In the device, the first loopback address of the first network device and the second loopback address of the second network device are used as addresses for the first network device and the second network device to establish border BGP neighbors, wherein the first network device may be as figure 1 In the shown SW1, the second network device may be SW2 / 3, and the second network device is referred to as SW2 for illustration below. The procedure of this method is as follows Figure 4 As shown, the execution steps are as follows:

[0052] S41: After detecting that the BGP link with the second network device is disconnected, calculate the recursive next hop of the second loopba...

Abstract

The invention discloses a routing management method and device, the method comprising: after detecting that the BGP link with the second network device is disconnected, calculating the recursive next hop of the second loopback address; Determine whether the recursive next hop of the second loopback address is a host route; if it is determined that the recursive next hop of the second loopback address is not a host route, cancel the second loopback address from the software routing table address as the first route for the recursive next hop; instruct the hardware routing table to withdraw the first route. This solution can avoid routing loops, and also avoid 180-second packet loss, which can meet the high-bandwidth, low-latency business standards of the data center, and greatly improve user experience.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a routing management method and device. Background technique [0002] With the continuous development and expansion of the data center network, the data center basically uses an Exterior Border Gateway Protocol (Exterior Border Gateway Protocol, EBGP) layered network to build a basic network. More and more data centers use routing protocols to quickly switch the three-layer Internet Protocol (IP) network in the data center, and the Border Gateway Protocol (Border Gateway Protocol, BGP) has become the best choice for the routing protocol of the data center. [0003] Such as figure 1 As shown, in order to ensure the availability of the data center, when it is necessary to notify the IP address (Address 1) of a certain server, a multi-network device (Switch-2 / 3, hereinafter referred to as SW2 / 3) and an uplink network device (Switch-1, hereinafter referred to as SW1 for shor...
