How to use the Looking Glass through SSH

The NLNOG RING offers a looking glass, solely accessible through SSH by RING users! You can ssh to Don’t forget to use the proper username! If you ssh to this host you should drop straight to a dialog menu, where you can select either IPv4 or IPv6. Here are some pointers how to retrieve information:

  • Show detailed information for a prefix or IP:
    show route for all
  • Show all routes originated by AS15562:
    show route where bgp_path.last = 15562
  • Show all routes which have AS5580 in the path:
    show route where bgp_path ~ [= * 5580 * =]
  • Equivalent of show bgp sum:
    show protocols

Currently the ring is using BIRD as the BGP speaker, it might take some getting used to get valuable information out of it. ;-)
