Basic configuration tasks required for BGP4
• If you add a parameter to a peer group that already contains neighbors, the parameter value is
applied to neighbors that do not already have the parameter explicitly set. If a neighbor has the
parameter explicitly set, the explicitly set value overrides the value you set for the peer group.
• If you remove the setting for a parameter from a peer group, the value for that parameter
changes to the default value for all the neighbors in the peer group that do not have that
parameter individually set.
Configuring a peer group
To configure a BGP4 peer group, enter commands such as the following at the BGP configuration
level.
Brocade(config-bgp-router)#neighbor PeerGroup1 peer-group
Brocade(config-bgp-router)#neighbor PeerGroup1 description “EastCoast Neighbors”
Brocade(config-bgp-router)#neighbor PeerGroup1 remote-as 100
Brocade(config-bgp-router)#neighbor PeerGroup1 distribute-list out 1
The commands in this example configure a peer group called “PeerGroup1” and set the following
parameters for the peer group:
• A description, “EastCoast Neighbors”
• A remote AS number, 100
• A distribute list for outbound traffic
The software applies these parameters to each neighbor you add to the peer group. You can
override the description parameter for individual neighbors. If you set the description parameter for
an individual neighbor, the description overrides the description configured for the peer group.
However, you cannot override the remote AS and distribute list parameters for individual neighbors.
Since these parameters control outbound traffic, the parameters must have the same values for all
neighbors within the peer group.
Syntax: neighbor peer-group-name peer-group
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.
