Embodiment Construction
[0020] figure 1 It is a flow chart of a method for processing the routing next hop provided by the embodiment of the present invention. Such as figure 1 As shown, the method includes:
[0021] 101. When it is determined to add a first next-hop entry in the hardware routing table, determine whether there is a next-hop entry with the same key as the first next-hop entry in the hardware routing table, the The first next hop entry refers to the next hop entry corresponding to the first neighbor of the dual-stack user; if the determination result is no, it is determined that there is no keyword and the first next For the next hop entry that is the same as the first hop entry, execute 102; if the determination result is yes, it is determined that there is a next hop entry with the same key as the first next hop entry in the hardware routing table , go to step 103.
[0022] 102. Add the first next-hop entry to the hardware routing table, and set the state flag of the first next-h...

The invention provides a method, device and network equipment for processing the next hop of routing. The method includes: when determining to add a first next-hop entry corresponding to the first neighbor of the dual-stack user in the hardware routing table, determining whether there is a next-hop entry with the same keyword as the first next-hop entry in the hardware routing table One-hop entry; if it does not exist, add the first next-hop entry in the hardware routing table, and set the status flag of the first next-hop entry so that the first next-hop entry only corresponds to the first neighbor ; If it exists, then set the state flag of the existing next-hop entry, so that the existing next-hop entry corresponds to the first neighbor and the second neighbor at the same time; wherein, the first neighbor is an IPv4 neighbor and an IPv6 neighbor One of the neighbors, the second neighbor is another. The technical scheme of the invention can realize the sharing of next-hop table items between IPv4 neighbors and IPv6 neighbors, and solves the problem of insufficient resources of next-hop table items in the hardware routing table.
Description
technical field [0001] The invention relates to communication technology, in particular to a method, device and network equipment for processing the next hop of routing. Background technique [0002] With the popularization of Internet Protocol Version 6 (Internet Protocol Version 6, IPv6 for short), there are more and more Internet Protocol Version 4 (Internet Protocol Version 4, IPv4 for short) / IPv6 dual-stack users. In an IPv4 / IPv6 dual-stack application environment, after the device learns an IPv4 neighbor, it adds the corresponding next-hop entry to the next-hop entry resource of the hardware routing table. The corresponding next hop entry is added to the next hop entry resource of the routing table. [0003] In a large convergence flat network environment, if an IPv4 / IPv6 dual-stack user goes online, an IPv4 next-hop entry and an IPv6 next-hop entry must be added for the user on the large convergence gateway device, which will As a result, the resources of the next h...
