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 the following server:


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. ;-)
