peer listen-only (BGP view) (IPv6)

Function

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

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

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

peer ipv6-address { listen-only | connect-only }

Usage Guidelines

Usage Scenario

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

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

Configuration Impact

If the peer listen-only command is run multiple times, the latest configuration overwrites the previous one.

After being configured with the peer listen-only 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.

Example

# Enable peer to send connection requests but rejects connection requests.

<HUAWEI> system-view
[~HUAWEI] bgp 100
[*HUAWEI-bgp] peer 2001:DB8:1::1 as-number 200
[*HUAWEI-bgp] peer 2001:DB8:1::1 connect-only
