Configuring a large-scale IPv6 BGP network

In a large-scale IPv6 BGP network, configuration and maintenance become inconvenient because of
too many peers. Configuring peer groups makes management easier and improves route distribution
efficiency. Peer groups include IBGP peer groups, where peers belong to the same AS, and EBGP
peer groups, 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 have a common policy. Using the COMMUNITY attribute can make a
set of IPv6 BGP routers in multiple ASs have the same policy, because community sending between
IPv6 BGP peers is not limited by AS.
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.

Configuration 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.
