| Resolution: |
BGP information such as AS Path, BGP Community, AS Origin, Local AS, No Advertise, No Export, and No Peer is part of the BGP communication protocol. Flowmon Probe does not parse BGP protocol on the L7 level, and we are not aware of any third-party flow source exporting this information. Flowmon Collector is able to collect information about the source/destination AS number, BGP next hop IP, and BGP adjacent next/previous AS. Next hop IP and adjacent AS numbers have to be exported by routers (included in flow data). If routers export this information, it has to be enabled also on the Flowmon Collector in Configuration Center - FMC Configuration - Flow database fields - BGP next HOP IP address, BGP adjacent prev/next AS. |
