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.

Configuring IPv6 BGP Peer Group

Configuring an iBGP peer group
Follow these steps to configure an iBGP group:
To do...
Enter system view
Enter BGP view
Enter IPv6 address family view
Create an iBGP peer group
Add a peer into the group
Use the command...
balance number
Use the command...
system-view
bgp as-number
ipv6-family
group ipv6-group-name
[ internal ]
peer ipv6-address group
ipv6-group-name [ as-number
as-number ]
1-15
