**Table 1** Description of the **display bgp ipv6 peer verbose** command output
Item	Description
BGP version	BGP version.
BGP current state	State of BGP: 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 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.
BGP Peer is	Peer address.
Peer Preferred Value	PrefVal of the peer.
Peer optional capabilities	Optional capabilities of the peer.
Remote router ID	Router ID of the peer.
Update-group ID	ID of the update-group to which the peer belongs.
Received total routes	Number of received route prefixes.
Received active routes total	Number of received active route prefixes.
Received : Active Hold Time:	Hold time on the peer.
Received	Number of messages received from a peer. Total: indicates the total number of messages received from a peer. Update messages: indicates the number of Update messages received from a peer. Open messages: indicates the number of Open messages received from a peer. KeepAlive messages: indicates the number of Keepalive messages received from a peer. Notification messages: indicates the number of Notification messages received from a peer. Refresh messages: indicates the number of route-refresh messages received from a peer.
Advertised total routes	Number of sent route prefixes.
Keepalive Time	Indicates the interval at which Keepalive messages are sent to the peer.
Negotiated: Active Hold Time:	Hold time agreed between the BGP peers after capability negotiation.
Address family IPv6 Unicast	IPv6 unicast address family.
Authentication type configured	Authentication type.
Last keepalive received	Last time when a Keepalive message is received.
Last keepalive sent	Last time when a Keepalive message is sent.
Minimum route advertisement interval	Minimum route advertisement interval. The minimum interval at which EBGP routes are advertised is 30 seconds. The minimum interval at which IBGP routes are advertised is 15 seconds.
Optional capabilities	(Optional) Peer-supported capabilities.
Route refresh capability has been enabled	Route refreshing has been enabled.
Memory Priority	The priority for a BGP peer relationship to be disconnected if memory overload occurs.
Routing policy configured	Configured routing policy.
Type	BGP link type: IBGP or EBGP.
Port	Port type: Local: indicates the local port number, which is always 179. BGP uses TCP at the transport layer. Remote: indicates the port number used on the peer.
Configured	Locally configured timers. Active Hold Time: indicates the hold time. If BGP does not receive any Keepalive message from the peer in the hold time, BGP considers that the peer is Down and then instructs other peers to remove the routes that are sent from the peer. Keep Alive Time: indicates the interval at which Keepalive messages are sent to the peer. BGP peers exchange Keepalive messages periodically to maintain their relationships.
Sent	Number of messages sent to a peer. Total: indicates the total number of messages sent to a peer. Update messages: indicates the number of Update messages sent to a peer. Open messages: indicates the number of Open messages sent to a peer. KeepAlive messages: indicates the number of Keepalive messages sent to a peer. Notification messages: indicates the number of Notification messages sent to a peer. Refresh messages: indicates the number of route-refresh messages sent to a peer.
