Usage Guidelines

Usage Scenario

The display bgp vpn-target peer verbose command can be used for troubleshooting, with details as follows: If BGP peers are disconnected, specify log-info in the command to check the log information of the specified peer. In the command output, Date/Time indicates the time when the peers were disconnected, and Error Code and Error Subcode indicate the cause of the disconnection.

Precautions

To view detailed information about a BGP peer, such as information about BGP timers, the number of sent and received routes, capacities supported, the number of sent and received BGP messages, and enabled functions, specify verbose in the command.

Example

The actual command output varies according to the device. The command output here is only an example.

**Table 1** Description of the **display bgp vpn-target peer verbose** command output
Item	Description
BGP Peer	IP address of the BGP peer.
BGP version	BGP version.
BGP current state	Status the BGP peer: Idle: BGP denies any connection request. This is the initial status of BGP. Active: BGP tries to establish a TCP connection. This is the intermediate status of BGP. Connect: BGP is waiting for the establishment of the TCP connection to complete before performing further actions. OpenSent: BGP is waiting for an Open message from the peer. OpenConfirm: BGP is waiting for a Notification message or a Keepalive message. Established: BGP peers can exchange Update, Notification, and Keepalive messages. No neg: The address family is not enabled for the BGP peer. In this state, Update messages can be exchanged in other address families whose capabilities have been successfully negotiated. If the address family is enabled for the BGP peer, the local BGP peer receives a Notification message, and the peer relationship is disconnected. Then, the BGP peer changes to the Idle state and re-establishes the peer relationship.
BGP current event	Current BGP event.
Peer supports bgp multi-protocol extension	The BGP peer supports MP-BGP.
Peer supports bgp route refresh capability	The BGP peer supports route-refresh.
Peer Preferred Value	Preferred value of the BGP peer.
remote AS	The AS Number of the peer.
Remote router ID	Router ID of the peer.
Update-group ID	Update group ID of the BGP peer.
Received : Active Hold Time	Hold time of the BGP peer.
Received	Number of messages received from the BGP peer: Total: indicates the total number of messages. Update messages: indicates the number of Update messages. Open messages: indicates the number of Open messages. KeepAlive messages: indicates the number of Keepalive messages. Notification messages: indicates the number of Notification messages. Refresh messages: indicates the number of route-refresh messages.
Negotiated: Active Hold Time	Hold time negotiated with the BGP peer.
Minimum route advertisement interval is 30 seconds	Minimum route advertisement interval: EBGP: 30s. IBGP: 15s.
Optional capabilities	Optional capabilities supported by the BGP peer.
Route refresh capability has been enabled	Route-refresh is enabled.
Memory Priority	The priority for a BGP peer relationship to be disconnected if memory overload occurs.
Routing policy configured	Routing policy configured.
Type	BGP link type, which can be either IBGP Link or EBGP Link.
Port	Port number: Local: local port number, which is fixed at 179 because BGP uses TCP as the transport layer protocol. Remote: port number of the BGP peer.
Configured	Timers that are locally configured: Active Hold Time: indicates the hold time. If BGP does not receive any Keepalive messages from the BGP peer in the hold time, BGP considers that the peer is Down. BGP then instructs the other peers to withdraw the routes received from this peer. Keep Alive Time: indicates the interval for sending Keepalive messages to the BGP peer. BGP peers exchange Keepalive messages periodically, indicating that they are normal.
Sent	Number of messages sent to the BGP peer: Total: indicates the total number of messages. Update messages: indicates the number of Update messages. Open messages: indicates the number of Open messages. KeepAlive messages: indicates the number of Keepalive messages. Notification messages: indicates the number of Notification messages. Refresh messages: indicates the number of route-refresh messages.
