**Table 1** Description of the **display bgp l2vpn-ad peer verbose** command output
Item	Description
BGP Peer is 10.1.1.1	The address of BGP peer.
BGP version	BGP version.
BGP current state	Status of the peer: Idle: indicates that BGP denies any request of entering. This is the initiatory status of BGP. Upon receiving a Start event, BGP initiates a TCP connection request to the remote BGP peer, starts the ConnectRetry Timer with the initial value, listens for a TCP connection request initiated by the remote BGP peer, and changes its state to Connect. Connect: indicates that BGP is waiting for the TCP connection to be set up before it determines whether to perform other operations. If the TCP connection succeeds, BGP stops the ConnectRetry Timer, sends an Open message to the remote peer, and changes its state to OpenSent. If the TCP connection fails, BGP restarts the ConnectRetry Timer with the initial value, continues to listen for a TCP connection request initiated by the remote peer, and changes its state to Active. If the ConnectRetry Timer has expired before a TCP connection is established, BGP restarts the timer with the initial value, initiates a TCP connection request to the remote BGP peer, and stays in the Connect state. Active: indicates that BGP tries to set up a TCP connection. This is the intermediate status of BGP. If the TCP connection succeeds, BGP stops the ConnectRetry Timer, sends an Open message to the remote peer, and changes its state to OpenSent. If the ConnectRetry Timer has expired before a TCP connection is established, BGP restarts the timer with the initial value and changes its state to Connect. If BGP initiates a TCP connection request with an unknown IP address, the TCP connection fails. When this occurs, BGP restarts the ConnectRetry Timer with the initial value and stays in the Active state. OpenSent: indicates that BGP has sent one Open message to its peer and is waiting for the other Open message from the peer. If there are no errors in the Open message received, BGP changes its state to OpenConfirm. If there are errors in the Open message received, BGP sends a Notification message to the remote peer and changes its state to Idle. If the TCP connection fails, BGP restarts the ConnectRetry Timer with the initial value, continues to listen for a TCP connection request initiated by the remote peer, and changes its state to Active. OpenConfirm: indicates that BGP is waiting for a Notification or Keepalive message. If BGP receives a Notification message, or the TCP connection fails, BGP changes its state to Idle. If BGP receives a Keepalive message, BGP changes its state to Established. Established: indicates that BGP peers can exchange Update, Notification, and Keepalive messages. If BGP receives an Update or a Keepalive message, its state stays in Established. If BGP receives a Notification message, BGP changes its state to Idle. 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.
BGP last state	Last BGP status, which may be Idle, Connect, Active, OpenSent, OpenConfirm, Established or No neg.
BGP Peer Up count	Flapping count of a BGP peer in a specified period of time.
Peer Preferred Value	PrefVal of the peer.
remote AS 100	The number of remote AS.
Update-group ID	ID of the update-group to which the peer belongs.
Configured: Connect-retry Time	Locally configured connect-retry timer.
Configured: Min Hold Time	Locally configured minimum hold timer.
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.
Authentication type configured	Authentication type that is configured.
Last keepalive received	Time when a Keepalive message was last received.
Last keepalive sent	Time when a Keepalive message was last sent.
Last update received	Time when an Update message was last received.
Last update sent	Time when an Update message was last sent.
Last refresh received	Time when an route-refresh message was last received.
No refresh sent since peer has been configured	No Route-Refresh messages have been sent to the peer since the peer relationship was established.
Minimum route advertisement interval is 15 seconds	Minimum route advertisement interval.
Optional capabilities	Optional capabilities of the peer.
Route refresh capability has been enabled	The Route-Refresh has been enabled.
4-byte-as capability has been enabled	The 4-byte AS capability has been enabled.
Memory Priority	The priority for a BGP peer relationship to be disconnected if memory overload occurs.
Routing policy configured	Whether a route-policy has been configured.
Type	BGP link type: IBGP or EBGP.
Received	Number of messages received from a peer.
Sent	Number of messages sent to a peer.
Signaling	The signaling protocol used.
Configured	Timer that is locally configured: Active Hold Time: indicates the hold time. If BGP does not receive any Keepalive message from a peer within the hold time, BGP considers the peer Down and instructs other peers to withdraw the routes received from this peer. Keep Alive Time: indicates the interval at which Keepalive messages are sent to a peer. BGP peers exchange Keepalive messages periodically to show that they are working normally.
