peer listen-only (BGP-VPN instance IPv6 address family view) (group)

Function

The peer listen-only command configures a peer group to only listen to connection requests and not to initiatively send connection requests.

The undo peer listen-only command cancels the function.

The peer connect-only command configures a peer group to send connection requests but rejects connection requests.

The undo peer connect-only command restores the default setting.

By default, a peer group listens to and sends connection requests and a peer group listens to, accepts, and proactively sends connection requests.

peer group-name { listen-only | connect-only }

undo peer group-name { listen-only | connect-only }

Usage Guidelines

Usage Scenario

The peer listen-only command is used to configure a peer group to only listen to connection requests and not to initiatively send connection requests.

The peer connect-only command is used to configure a peer group to send connection requests but rejects connection requests.

Configuration Impact

If this command is run multiple times, the latest configuration overwrites the previous one.

After being configured with this command, a peer does not initiate any connection request.

Precautions

The peer listen-only command can be run at only one end of a peer relationship. If this command is run at both ends of a peer relationship, the ends fail to establish a connection.

The peer connect-only command or the peer listen-only command cannot be run on two devices that will establish a peer relationship. Otherwise, no peer relationship can be established between the two devices.
