BGP and BGP4+ Introduction
How to configure BGP and BGP4+
This section describes BGP and BGP4+ configuration tasks and the commands required. For example configurations with sample topologies, see Chapter 2, BGP and BGP4+ Configuration.
Initial BGP and BGP4+ Configuration Tasks
There are two initial BGP and BGP4+ configuration tasks described in the below sections. More advanced BGP and BGP4+ configuration tasks are described later in this chapter and are also available separately in the How to Configure BGP and BGP4+ Technical Guide:
■How to enable BGP and BGP4+ Routing
■How to configure BGP and BGP4+ Neighbors
How to enable BGP and BGP4+ Routing
To enable BGP or BGP4+ routing and establish a BGP or BGP4+ routing process, use the following commands starting in Global Configuration mode:
awplus(config)#
router bgp <asn> This command enables a BGP or BGP4+ routing process, which places the router in Router Configuration mode.
awplus(config-router)#
network
network
This command flags an IPv6 network as local to this autonomous system and enters it to the BGP4+ table.
How to configure BGP and BGP4+ Neighbors
Like other EGPs, BGP must completely understand the relationships it has with its neighbors. Therefore, this task is required.
BGP supports two kinds of neighbors: internal and external. Internal neighbors are in the same autonomous system; external neighbors are in different autonomous systems. Normally, external neighbors are adjacent to each other and share a subnet, while internal neighbors may be anywhere in the same autonomous system.
To configure BGP neighbors, use the following command in Router Configuration mode:
neighbor <neighborid>
