  • Fast routing convergence for border gateway protocl (BGP) systems including one or more route reflectors (RRs)
    Patent number: 11050681
    Abstract: Responsive to receiving the BGP UPDATE message, a route reflector may (1) update 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, and (2) send the revised BGP UPDATE message to a client of the route reflector, regardless of whether or not one of (A) field validity checking of the BGP UPDATE message, (B) Adj-RIBS-In update using the BGP UPDATE message, (C) decision processing for route selection using information in the BGP UPDATE message, or (D) Adj-RIBS-Out update using the BGP UPDATE message, is completed (or perhaps even started). This provides faster route propagation and avoids delays associated with processing BGP UPDATE messages (NLRI with advertisements and withdrawals) at each hop the NLRIs using conventional BGP such as next-hop validation, best path selection, etc.
