The | 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 IP address, you are configuring that individual neighbor. Use the parameter if
you are configuring an individual neighbor instead of a peer group. Refer to
“Adding BGP4
neighbors” on page 671.
The remaining parameters are the same ones supported for individual neighbors. Refer to “Adding
BGP4 neighbors” on page 671.
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.
TurboIron(config-bgp-router)#neighbor 192.168.1.12 peer-group PeerGroup1
TurboIron(config-bgp-router)#neighbor 192.168.2.45 peer-group PeerGroup1
TurboIron(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 (except parameters that govern outbound
traffic) on an individual neighbor basis. For neighbor parameters not specified for the peer group,
the neighbors use the default values.
Syntax: neighbor peer-group
The parameter specifies the IP address of the neighbor.
The 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 Layer 3 Switch 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 Layer 3 Switch, configure the neighbor
parameters, then allow the Layer 3 Switch to re-establish a session with the neighbor by removing
the shutdown option from the neighbor.
