The <ip-addr> | <peer-group-name> parameter indicates 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’s 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. Refer to
“Configuring a BGP4 peer group”
The remaining parameters are the same ones supported for individual neighbors. Refer to
on page 846 and
“Configuring a BGP4 peer group”
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.
BigIron RX(config-bgp)# neighbor 192.168.1.12 peer-group PeerGroup1
BigIron RX(config-bgp)# neighbor 192.168.2.45 peer-group PeerGroup1
BigIron RX(config-bgp)# 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: 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 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 new option to shut down a neighbor, the option takes place immediately and
remains in effect until you remove the option. If you save the configuration to the startup
configuration file, the shutdown option remains in effect even after a software reload.
