Before configuring a large-scale BGP network, you need to prepare the following
data:
z Peer group type, name, and the peers included.
z If you want to use community, the name of the applied routing policy is needed.
z If you want to use RR, you need to determine the roles (client, non-client) of
routers.
z If you want to use confederation, you need to determine the confederation ID and
the sub-AS number.
