Abstract
A system and method is directed to synchronizing a standby route distributor in a distributed routing platform. A route distributor is configured to operate as an active route distributor. Another route distributor is configured to operate as a standby route distributor. The standby and active route distributor may reside in the same or a different distributed routing platform. A slave route distributor communicates a route to the active route distributor. The active route distributor may update its routing tables with the route. The active route distributor forwards the route to the standby route distributor to enable their routing tables to be substantially synchronized. The standby route distributor distributes the route to the slave route distributors, where the route enables an update to another routing table. In the event of a switchover, the standby route distributor resynchronizes its routing tables and may distribute route information to each slave route distributor.
