    Hello Arix,

     

    you can check if you receive or advertise prefixes to your BGP neighbors with the following commands:

     

    Check if you receive a prefix from neighbor 1.1.1.1:

    show route receive-protocol bgp 1.1.1.1 <optional: prefix you want to check>

    Check if you advertise a prefix to neighbor 1.1.1.1:

    show route advertising-protocol bgp 1.1.1.1 <optional: prefix you want to check>
