# neighbor activate

#### Syntax

[ no | default ] neighbor { ipAddress | ipv6Address | peerGroupName } activate

#### Release Information

Command introduced before JunosE Release 7.1.0.
ipv6Address variable added in JunosE Release 8.0.0.

#### Description

Specifies a peer or peer group with which routes of the current address family are exchanged. A peer or peer group can be activated in more than one address family. By default, a peer or peer group is activated only for the IPv4 unicast address family. The address families that are actively exchanged over a BGP session are negotiated when the session is established. This command takes effect immediately. The no version indicates that routes of the current address family should not be exchanged with the peer or peer group. The default version removes the explicit configuration from the peer or peer group and reestablishes inheritance of the feature configuration.

#### Options

- ipAddress—IP address of BGP neighbor
- ipv6Address—IPv6 address of BGP neighbor
- peerGroupName—Name of a BGP peer group. If you specify a BGP peer group by using the peerGroupName argument, all the members of the peer group inherit the characteristic configured with this command, unless it is overridden for a specific peer.

#### Mode

Address Family Configuration, Router Configuration
