Release Information

Statement introduced before JUNOS Release 7.4.

Statement introduced in JUNOS Release 9.0 for EX Series switches.


Explicitly configure a neighbor (peer). To configure multiple BGP peers, include multiple neighbor statements.

By default, the peer’s options are identical to those of the group. You can override these options by including peer-specific option statements within the neighbor statement.

The neighbor statement is one of the statements you can include in the configuration to define a minimal BGP configuration on the routing device. (You can include an allow all statement in place of a neighbor statement.)


address—IPv6 or IPv4 address of a single peer.

The remaining statements are explained separately.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.
