The ip-addr and peer-group-name parameters indicate whether you are configuring a peer group or an individual neighbor. You can
specify a peer group name or IP address with the neighbor command. If you specify a peer group name, you are configuring a peer
group. If you specify a neighbor IP address, you are configuring that individual neighbor. Use the ip-addr parameter if you are configuring
an individual neighbor instead of a peer group.
The remaining parameters are the same ones supported for individual neighbors.
Applying a peer group to a neighbor
After you configure a peer group, you can add neighbors to the group. When you add a neighbor to a peer group, you are applying all the
neighbor attributes specified in the peer group to the neighbor.
To add neighbors to a peer group, enter commands such as the following.
device(config-bgp-router)# neighbor 192.168.1.12 peer-group PeerGroup1
device(config-bgp-router)# neighbor 192.168.2.45 peer-group PeerGroup1
device(config-bgp-router)# neighbor 192.168.3.69 peer-group PeerGroup1
The commands in this example add three neighbors to the peer group "PeerGroup1". As members of the peer group, the neighbors
automatically receive the neighbor parameter values configured for the peer group. You also can override the parameters on an individual
neighbor basis. For neighbor parameters not specified for the peer group, the neighbors use the default values.
Syntax: [no] neighbor ip-addr peer-group peer-group-name
The ip-addr parameter specifies the IP address of the neighbor.
The peer-group-name parameter specifies the peer group name.
NOTE
You must add the peer group before you can add neighbors to it.
Administratively shutting down a session with a BGP4 neighbor
You can prevent the device from starting a BGP4 session with a neighbor by administratively shutting down the neighbor. This option is
very useful for situations in which you want to configure parameters for a neighbor, but are not ready to use the neighbor. You can shut
the neighbor down as soon as you have added it to the device, configure the neighbor parameters, then allow the device to reestablish a
session with the neighbor by removing the shutdown option from the neighbor.
When you apply the option to shut down a neighbor, the option takes place immediately and remains in effect until you remove it. If you
save the configuration to the startup configuration file, the shutdown option remains in effect even after a software reload.
The software also contains an option to end the session with a BGP4 neighbor and clear the routes learned from the neighbor. Unlike
this clear option, the option for shutting down the neighbor can be saved in the startup configuration file and can prevent the device from
establishing a BGP4 session with the neighbor even after reloading the software.
NOTE
If you notice that a particular BGP4 neighbor never establishes a session with the device, check the running configuration and
startup configuration files for that device to see whether the configuration contains a command that is shutting down the
neighbor. The neighbor may have been shut down previously by an administrator.
To shut down a BGP4 neighbor, enter commands such as the following.
device(config)# router bgp
device(config-bgp-router)# neighbor 10.157.22.26 shutdown
device(config-bgp-router)# write memory
