Worth Reading: pbgpp

pbgpp allows network operators to apply a wide range of filters, either on network layer (src IP, dst IP), but foremost BGP fields — for example, prefix, communities, or next hop. Filters are applied in two steps, improving analysis performance. Before parsing the BGP-specific fields in the captured packet, lower-layer packet header field filters (IP or MAC source or destination) are applied. Thus, we do not parse all packets, but only the matching ones. BGP-specific filters are applied subsequently after parsing. —APNIC
