FAST ROUTING CONVERGENCE FOR BORDER GATEWAY PROTOCL (BGP) SYSTEMS INCLUDING ONE OR MORE ROUTE REFLECTORS (RRs)

A system comprising:

• a) a route reflector having
• 1) at least one processor;
• and
• 2) a non-transitory computer-readable medium storing processor-executable instructions which, when executed by the at least one processor, cause the at least one processor to perform a method including
• A) receiving, by a route reflector, a border gateway protocol (BGP) UPDATE message;
• and
• B) responsive to receiving the BGP UPDATE message,
• i) updating, by the route reflector, a CLUSTER_LIST value and, if needed, an ORIGINATOR_ID value, in a path attribute section in the BGP UPDATE message to generate a revised BGP UPDATE message,
• ii) sending, by the route reflector, the revised BGP UPDATE message to a client of the route reflector, regardless of whether or not one of
• field validity checking of the BGP UPDATE message,
• Adj-RIBS-In update using the BGP UPDATE message,
• decision processing for route selection using information in the BGP UPDATE message, or
• Adj-RIBS-Out update using the BGP UPDATE message,
• is completed.
