description The invention provides a fast route switching method and device based on BGP networking. The method comprises the following steps: dividing a target autonomous system (AS) into a plurality of AS subgroups and pairing the AS subgroups in pairs; configuring a group of routing reflectors (RR) for each AS subgroup pair, and configuring a BGP network from a target AS to a destination AS; in the BGP networking, each AS subgroup pair and a target AS are connected with a group of RRs, a first RR in the group of RRs is a main RR of a first AS subgroup in the AS subgroup pair, a standby RR of a second AS subgroup in the AS subgroup pair, and a second RR in the group of RRs is vice versa; when the main RR of each AS subgroup operates normally, the main RR maintains the first routing information of the AS subgroup; and when the main RR fails, switching the standby RR of the AS subgroup to maintain the first routing information of the AS subgroup. According to the invention, the complexity of BGP networking between differ
