What is a looking glass in networking?
Looking glasses are web scripts directly connected to routers’ admin interfaces such as telnet and SSH. These scripts are designed to relay textual commands from the web to the router and print back the response. The are often implemented in Perl PHP, and Python, and are publicly available on GitHub.
What is a route server used for?
What Are Route Servers? Route servers are servers (not routers) that simplify the exchange of routing information between networks. The information is shared using Border Gateway Protocol (BGP), the same protocol used by LINX members for peering.
What is BGPlay?
BGPlay is a tool which displays animated and interactive graphs of the interdomain routing activity in Internet of a certain prefix within a specified time interval.
What’s the difference between a Looking Glass and a route server?
The difference between a public route server and a looking glass (aside from an LG having a nifty CGI) is that a wide variety of networks (including some tier one carriers) peer with a route server, so there’s an “overall” bigger picture of which prefixes are coming from which ASN’s.
What are Looking Glass servers and how to use them?
Looking Glass servers are deployed in different parts of the Internet and allow on-line checking of prefixes, collected from the BGP speaking routers. LGs make network administrators more effective during troubleshooting, helping them “see” their prefixes from the “outside”.
How are looking glasses connected to the router?
Looking glasses are web scripts directly connected to routers’ admin interfaces such as telnet and SSH. These scripts are designed to relay textual commands from the web to the router and print back the response.
How are Looking Glass servers used in BGP?
BGP Software Tools & Scripts. BGP Looking Glass servers are computers on the Internet running one of a variety of publicly available Looking Glass software implementations. A Looking Glass server (or LG server) is accessed remotely for the purpose of viewing routing info.
