BGP LookinGlass Question

Joshua Engels

Hey guys,

I just recently setup two 2911 Routers on two different service providers with BGP advertising one prefix.  I have heard about something called BGP lookinglass and was wondering if you guys could shed some light on what this can do for me in my testing as well as what is a good site to use.  Any information will be helpful to get me going in the right direction. 

Thanks.

BGP looking glass is a really useful tool. Many ISPs host their own and allow public access to them.

Some are just web pages which allow you to search an IP and show the possible AS paths to that IP, others use a command line interface which looks and feels like a cisco router, from here you can run your 'sh ip bgp' commands.

Have a look at http://www.bgp4.as/looking-glasses for some looking glass servers.

Hi,

This is something different and relates to ISP environment. These typicall run by their NOCs.

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. Essentially, the server acts as a limited, read-only portal to routers of whatever organization is running the Looking Glass server. Typically, publicly accessible looking glass servers are run by ISPs or NOCs.

This page presents an overview of BGP Looking Glasses all over the world. If you'd like to install a BGP Looking Glass in your ISP environment, you will find several Looking Glass implementations in any BGP Software section.

There are multiple of them here.

Personally, I prefer route-servers. One of them is available at: telnet://route-views.on.bb.telus.com
