Configuring a large scale BGP network
In a large-scale BGP network, configuration and maintenance may become difficult due to large
numbers of BGP peers. To facilitate configuration, you can configure peer group, community, route
reflector or confederation as needed.
Configuration prerequisites
Peering nodes are accessible to each other at the network layer.
Configuring BGP peer groups
A peer group is a group of peers with the same route selection policy.
In a large scale network, many peers may use the same route selection policy. You can configure a peer
group and add these peers into this group. In this way, peers can share the same policy as the peer
group. When the policy of the group is modified, the modification also applies to peers in it, simplifying
configuration.
A peer group is an IBGP peer group if peers in it belong to the same AS, and is an EBGP peer group if
peers in it belong to different ASs.
If a peer group has peers added, you cannot remove its AS number using the undo form of the command
or change its AS number.
1. Configure an IBGP peer group
After you create an IBGP peer group and then add a peer into it, the system creates the peer in
BGP view and specifies the local AS number for the peer.
To configure an IBGP peer group:
