Hio!

It depends what you are looking to troubleshoot.  BGP looking glasses provide you a view into the routing table (high level explanation) of the service provider.

This would allow you to perform some of the following troubleshooting:

- confirm that ISP is recieving your prefixes;

- confirm they are receiving/sending them with specific metrics (ie. Paths, PREF, Communities);

- What paths the ISP is using to reach your network;

Please rate helpful posts.
