Abstract

The invention discloses a method and a device for rapidly switching RIP (routing information protocol) routings. The method includes the steps: maintaining all RIP routings corresponding to the same destination address in an RIP routing table, selecting one optimal RIP routing from the RIP routings corresponding to the destination address and issuing the optimal RIP routing to a hardware forwarding table by a routing receiving device; inquiring the RIP routing issued by a routing issuing device from the RIP routing table when determining that a link corresponding to the routing issuing device is faulted by the routing receiving device; deleting the RIP routing from the RIP routing table if the RIP routing is not the optimal RIP routing; deleting the RIP routing from the RIP routing table, reselecting one optimal RIP routing from the other RIP routings corresponding to the RIP routing and issuing the reselected optimal RIP routing into the hardware forwarding table if the RIP routing is the optimal RIP routing. RIP routing switching time can be shortened, and flow loss time is further shortened.

Description

technical field

[0001] The invention relates to the technical field of communication, in particular to a method and device for fast switching of RIP routing. Background technique

[0002] RIP (Routing Information Protocol, Routing Information Protocol) is a protocol based on the distance vector algorithm, and uses the hop count to measure the distance to the destination address, which is the metric value. Among them, each network device running RIP manages a RIP routing table, which includes RIP routes to all reachable destination addresses, and the RIP routes include the following information: destination address, next-hop address (adjacent network interface address of the device), outbound interface (the outbound interface for forwarding packets on the network device), metric value (the cost of reaching the destination address), routing time (the time elapsed since the last update of the RIP route, and the RIP route When it is updated, the routing time is reset to 0), rou...
