Task
Add the sub-ASs as members of the
confederation. Every sub-AS within the
AS must be added as a confederation
member.
Using EBGP, configure the peering
session between the confederations
(from router A to router B in this
example).
When setting the peer AS number for
these sessions, use the sub-AS number
rather than the AS number.
Using IBGP, configure internal sessions
within a sub-AS. You can configure an
IBGP full mesh, or you can configure a
route reflector.
