To ensure connectivity between IBGP peers, make them fully meshed, but it becomes impractical when
too many IBGP peers exist. Using route reflectors or confederation can solve this issue. In a large-scale
AS, both of them can be used.
Confederation configuration of IPv6 BGP is identical to that of BGP4, so it is not mentioned here.
954BConfiguration prerequisites
Before you configure a large-scale IPv6 BGP network, complete the following tasks:
Make peer nodes accessible to each other at the network layer.
Enable BGP and configure a router ID.
