[ no | default ] neighbor { ipAddress | ipv6Address | peerGroupName } activate
Command introduced before JunosE Release 7.1.0.
ipv6Address variable added in JunosE Release 8.0.0.
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.
If dynamic capability negotiation was not negotiated with the peer, the session is
automatically bounced so that the exchanged address families can be renegotiated in
the open messages when the session comes back up.
If dynamic capability negotiation was negotiated with the peer, BGP sends a capability
message to the peer to advertise or withdraw the multiprotocol capability for the address
family in which this command is issued.
If a neighbor is activated, BGP also sends the full contents of the BGP routing table of
the newly activated address family.
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.
