BGP check neighbor advertising IPv4

Thu Aug 16, 2018 12:49 am

Hi All,

I have 2 IP transit providers for BGP routing.
I recently change my /24 IPv4 subnet and I put a request for change with both of them
I know one of them took action on the change request and the other didn`t
Is there a way to check witch one of them is actually advertising my subnet ?

Thank you!
Adrian

One of the best ways is to use a public route server. From there you can see what your prefixes look like advertised into the BGP global table

Also, BGPLay allows you to visualize subnets and connected ASes
