PCAP BGP Parser (pbgpp) is a PCAP parser to decode BGP messages collected with tcpdump. The parser reads PCAP input from file system, stdin, or by listening on a network interface. Furthermore, the parser is able to use several output filters and pipes to tailor the output for your individual needs. Therefore, we decided to develop PCAP BGP Parser aka pbgpp. The filters and pipes can be easily extended – we are happy to include your extensions any time.
