TRILL ISIS-BASED ROUTE CALCULATION METHOD AND DEVICE

摘要

Provided are a Transparent Interconnection of Lots of Links (TRILL) Intermediate System to Intermediate System (ISIS)-based route calculation method and device. The method includes that: a route calculation unit acquires a Link State Protocol Data Unit (LSP) packet from each Routing Bridge (RB) in a network (S102); and the route calculation unit calculates a routing table of each RB according to the LSP packet acquired from each RB, and sends the routing table to the corresponding RB (S104). The method solves the problem that a TRILL ISIS-based route calculation manner adopted in related technologies occupies considerable calculation resources and can be easily attacked. The method reduces the calculation resources occupied by the TRILL ISIS-based route calculation manner, and reduces the opportunities of attacking the TRILL ISIS since it is unnecessary in the present scheme to conduct mutual flooding and synchronization among various RB and save the LSP of other RB, thereby improving the stability and reliability of a system.
