I just have 2 routers on my lab, both are BGP speekers between (Private AS & Public AS).
every time my routers restarted, I can see (Bgp cluster ID) subcommand under my router bgp configuration.
1- can any one tell me why? and what is a cluster ID? although i didnt configure them on the routers.
2- also I need to know the range (number) for which a private AS begins to the end?
Appreciate your feedback,
