Abstract

The present invention provides a communication device and a method for generating a FIB table thereof. The method includes: when a target FIB table needs to be generated and the target FIB table points to multiple next hops, judging whether there are available ECMP resources and available ECMP Corresponding FEC resources; if there are available ECMP resources and available ECMP-corresponding FEC resources, then generate the target FIB table and synchronize to the forwarding chip; if there are no available ECMP resources or / and available ECMP-corresponding FEC resources , select one or more target next hops from the multiple next hops, generate FIB tables pointing to each target next hop and synchronize them to the forwarding chip. Applying the embodiment of the present invention can improve the probability of successfully generating the FIB table.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a communication device and a method for generating a FIB table thereof. Background technique [0002] The FIB (Forwarding Information Base, forwarding information base) table is used to guide IP (Internet Protocol, Internet Protocol) message forwarding. The router selects a route through the routing table, and sends the preferred route to the FIB table, and then the router can guide the forwarding of IP packets through the FIB table. Wherein, each forwarding entry in the FIB table indicates the next-hop IP address and the outgoing interface of the message to reach a certain subnet or a certain host. [0003] The FIB table usually points to a single next hop, but when there are multiple entries with the same address and the same cost, and the multiple routes have the same priority, the multiple routes will be used as ECMP (Equal-Cost Multipath, etc. valence path) t...
