Looking Glass

LG is a Looking Glass written in Perl as a CGI script. It can execute almost all BGP-related commands and do ping and traceroute in routers or relay these queries to other looking glasses. It supports both IPv4 and IPv6 commands, and is tested with Cisco, Zebra, and Juniper. It can connect to a router using SSH, telnet or rsh.
