A method is disclosed for providing prioritized routing table convergence
in Border Gateway Protocol (BGP) hosts, as part of a BGP process that is
executed by a route processor in a network, wherein the processor hosts a
plurality of BGP routing tables each associated with a specified
sub-address family (SAFI). A convergence priority order value is created
and stored in association with each routing table. As part of performing
a convergence phase of BGP processing, the convergence priority order
value of each routing table is obtained. The convergence phase is then
performed for the routing tables only according to an order that is
represented by the convergence priority order values. Therefore,
convergence proceeds more quickly and values needed by other routing
processes become available earlier.
