Find Source IP of Router for Route Learned via BGP

Unanswered Question

Hi All, 

45 minutes of searching documents and google, and I cannot find a series of commands that will help me identify the Source IP of the router which advertised a route.  The router I am accessing is the on-premise router, and only has one neighbor from which it learns all the routes. 

I recall being able to do this fairly easily in the past. 

Regards,
Jerry

To clarify, 

 

If I do

show ip bgp neighbor 10.100.100.2 route

I see about 100 routes learned from that neighbor. 

Is there any way to track down where each of those routes came from?

Thanks in advance,

Jerry

Hi, isn't traceroute good enough here? Best regards, Milan
