HP Link Discovery document:

HP have released a guide explaining how BDDP is used for link discovery on the HP VAN SDN Controller. This really guide is worth reading.

In the past, the HP controller used LLDP and BDDP messages for link discovery. This has changed and only BDDP is now used for link discovery. BDDP messages are proprietary.

The document explains concepts and shows wireshark captures for:

  • * Direct links
  • * Multiple-hop links

There is advice on the keys to correct link discovery as well as known issues.

These days I am involved in some exciting SDN and OpenFlow projects involving the HP VAN SDN Controller, HP ProVision and HP Comware switches. These new developments in the networking world combine my passions of networking and application development. I hope to write some interesting blog entries on these exiting topics. I am both a Cisco CCIE #11023 and HP MASE as well as a Cisco Certified Systems Instructor (CCSI #22787) and Certified HP Instructor. I have been training networking courses for well over 10 years teaching on a wide range of topics including routing and switching, VoIP, OpenFlow and SDN. I have delivered instructor led courses all over the world. I started working with Cisco Unified Communications Manager when it was still called Cisco Call Manager and have been deploying, troubleshooting and teaching Unified Communications products since version 3.0. I have developed various network utilities such as the VPN Config Generator and others to help engineers in their day to day jobs. I also develop software, training materials, EBooks, videos and other products which are used throughout the world. I have designed, implemented and managed networks ranging from single sites to those that span 50 countries.
