Embodiment Construction
[0059] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.
[0060] The invention discloses a local forwarding system for inter-device link aggregation, including a local forwarding system establishment stage and a local forwarding stage,
[0061] (1) Local forwarding system establishment stage
[0062] Such as Figure 6 As shown, the establishment of the forwarding system, that is, the process of synchronously learning the MAC address forwarding table between peer VAL devices.
[0063] 1. Create a VP mapping table
[0064] The VP mapping table is a configuration table, which is established when VAL rules are configured, and the mapping table is the same on the peer VAL devices. The content of the table entry is the corresponding relationship between VP and actual forwarding port (VAL Port or VAL INT Port), and the mapping between VP and VLANID (used to encapsulate VP into VAL TAG for transmission); Table...
