Basic configuration tasks required for BGP4
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.

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 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 “Adding BGP4
neighbors” on page 1354.
The remaining parameters are the same ones supported for individual neighbors. Refer to “Adding
BGP4 neighbors” on page 1354.
