US 2017/0302578 A1 · SYSTEM AND METHOD FOR BGP SFLOW EXPORT

Abstract

A method and apparatus of a device that exports Border Gateway Protocol (BGP) data in sFlow samples. The device generates separate tables for BGP attribute information, community list information, and autonomous systems path (AS_PATH) attribute information, where each entry in the BGP attribute information table is associated with an entry in the community list information table and an entry in the AS_PATH attribute information table. The device further populates a BGP route information table that defines a mapping from a network address prefix to an entry in the BGP attribute information table. The device generates 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.

Dependent claims

A non-transitory machine-readable medium having executable instructions to cause one or more processing units to implement a method to export routing protocol data, the method comprising:

generating a plurality of separate tables for the routing protocol data, wherein the routing protocol data is de-duplicated and at least one of the entries in a first one of the plurality of separate tables references a plurality of entries in other ones of the plurality of the separate tables;
populating a second one of the plurality of the separate tables with mapping information that defines a mapping from a network address prefix to an entry in the first one of the plurality of separate tables;
and
generating a routing protocol export sample related to the network address prefix using the plurality of separate tables.
