Configuring a Large Scale IPv6 BGP Network 
In a large-scale IPv6 BGP network, configuration and maintenance become no convenient due to too 
many peers. In this case, configuring peer groups makes management easier and improves route 
distribution efficiency. Peer group includes iBGP peer group, where peers belong to the same AS, and 
eBGP peer group, where peers belong to different ASs. If peers in an eBGP group belong to the same 
external AS, the eBGP peer group is a pure eBGP peer group, and if not, a mixed eBGP peer group.  
In a peer group, all members enjoy a common policy. Using the community attribute can make a set of 
IPv6 BGP routers in multiple ASs enjoy the same policy, because sending of community between IPv6 
BGP peers is not limited by AS.  
To guarantee connectivity between iBGP peers, you need to make them fully meshed, but it becomes 
unpractical when there are too many iBGP peers. Using route reflectors or confederation can solve it. 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. The 
following describes: 
Configuring IPv6 BGP peer groups 
Configuring IPv6 BGP community 
Configuring IPv6 BGP route reflectors 
Prerequisites 
Before configuring IPv6 BGP peer groups, you need to: 
Make peer nodes accessible to each other at the network layer 
Enable BGP and configure a router ID.
