Configuring a BGP4 peer group
26
The <peer-group-name> parameter specifies the name of the group and can be up to 80
characters long. The name can contain special characters and internal blanks. If you use internal
blanks, you must use quotation marks around the name. For example, the command neighbor “My
Three Peers” peer-group is valid, but the command neighbor My Three Peers peer-group is not
valid.
Syntax: [no] neighbor <ip-addr> |<peer-group-name>

[timers keep-alive <num> hold-time <num>]
[update-source loopback <num>]
[weight <num>]
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 BGP4
neighbors” on page 771 and “Configuring a BGP4 peer group” on page 778.
The remaining parameters are the same ones supported for individual neighbors. Refer to
“Configuring BGP4 neighbors” on page 771 and “Configuring a BGP4 peer group” on page 778.
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>
