Abstract:
1. A method for two-node cluster hot backup in a network, the network including a first network node having a first access port and a second network node having a second access port, the method comprising: configuring, by the second network node at the second access port, a redundancy protocol with the first network node to negotiate an active/standby relationship between the second access port and the first access port, wherein the second network node in communication with a user via the second access port, the first network node in communication with the user via the first access port, wherein the second access port serves as a standby access port of the first access port; advertising to a core network node, by the second network node, a second route for a network segment of the user, wherein a first route for the network segment of the user is advertised by the first network node to the core network node; synchronizing, by the second network node, user information with the first network node; and when the first network node has a failure, switching, by the second network node, service according to the redundancy protocol, and if downstream traffic to the user arrives at the second network node according to the second route, sending, by the second network node, the downstream traffic to the user via the second access port according to the user information.
