Claim of US Patent No. 9,722,925

1. A non-transitory machine-readable medium having executable instructions to cause one or more processing units to implement
a method to export Border Gateway Protocol (BGP) data in sFlow samples, the method comprising:
generating separate tables for BGP attribute information, community list information, and autonomous systems path (AS_PATH)
attribute information, each entry in the BGP attribute information table associated with an entry in the community list information
table and an entry in the AS_PATH attribute information table;

populating a BGP route information table that defines a mapping from a network address prefix to an entry in the BGP attribute
information table; and

generating a sFlow sample related to the network address prefix using the BGP attribute information table, the community list
information table, the AS_PATH attribute information table, and the BGP route information table.
