A method and device for accessing a network through multi-RB aggregation

Abstract

The present invention discloses a method and equipment for accessing a network through multi-RB aggregation. The method includes: when an RB learns the MAC address of an external network device from an RB aggregation port, the RB broadcasts a first RB aggregation message; When the RB receives the second RB aggregation message broadcast by other RBs, it maintains the correspondence between the domain identifier, MAC address and device identifier carried in the second RB aggregation message in the software forwarding entry; the RB When it is determined that other RBs are faulty, determine the domain identifiers corresponding to the other RBs that have failed, and update the device identifiers of the other RBs that have failed recorded in the hardware forwarding entry to the domains corresponding to the other RBs that have failed Identify the device ID of the RB that is not faulty corresponding to the software forwarding entry. In the embodiment of the present invention, link load sharing can be performed among multiple RBs, and traffic can be forwarded through the shortest path.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for accessing a network through multi-RB aggregation, in particular to a method and device for accessing a network through dual RB aggregation. Background technique [0002] Such as figure 1 As shown, it is a schematic diagram of a TRILL (TRansparent Interconnection of Lots of Links, multi-link transparent interconnection) network, RB1 (Route Bridge, routing bridge) is respectively connected to RB5, RB6 and RB7, and RB2 is respectively connected to RB5, RB6 and RB7 RB3 is connected with RB5, RB6 and RB7 respectively, and RB4 is connected with RB5, RB6 and RB7 respectively. For the traffic of RB1, RB2, RB3, and RB4, load sharing can be performed among RB5, RB6, and RB7. Any link failure or single-point failure will not affect the work of the entire TRILL network. However, if figure 1 As shown in the figure, when a host and a switch access RB...

Problems solved by technology

[0003] When the aggregation link of the IRF fails, the traffic cannot use the shortest path in the TRILL network, and the traffic will be forwarded through the stack link.
