Hi

I am not sure whether some of the AS numbers (private) are still in use or not on my MPLS WAN and if they can be reused.

Is there a way to find out unused BGP Autonomous System Numbers?

Thanks

Hi Sunil,

Simple thing will be to issue command "show ip bgp" on you BGP or mpBGP routers.

Regards,

Smitesh
