**Table 1** Description of the **display bgp evpn peer verbose** command output
Item	Description
BGP Peer is 3.3.3.3	Peer address (3.3.3.3 in this example).
BGP version	BGP version.
BGP current state	Current BGP EVPN status: Idle: BGP EVPN denies any connection request. This is the initial state of BGP EVPN. After BGP EVPN receives a start event, BGP EVPN initiates a TCP connection to a peer, starts the ConnectRetry timer, and listens to the TCP messages from the peer. BGP EVPN then enters the Connect state. Connect: BGP EVPN is waiting for the TCP connection establishment to complete before performing further actions. If the TCP connection is successfully established, BGP EVPN stops the ConnectRetry timer and sends an Open message to the peer. BGP EVPN then enters the Opensent state. If the TCP connection fails to be established, BGP EVPN resets the ConnectRetry timer and listens to the TCP connection initiated by the peer. BGP EVPN then enters the Active state. If the ConnectRetry timer expires, BGP EVPN restarts the ConnectRetry timer and attempts to establish a TCP connection with the peer again. At this time, BGP EVPN remains in the Connect state. Active: BGP EVPN attempts to establish a TCP connection. This is the intermediate state of BGP EVPN. If the TCP connection is successfully established, BGP EVPN resets the ConnectRetry timer and sends an Open message to the peer. BGP EVPN then enters the Opensent state. If the ConnectRetry timer expires, BGP EVPN restarts the ConnectRetry timer and enters the Connect state. If BGP EVPN attempts to establish a TCP connection with an unknown IP address but fails, BGP EVPN resets the ConnectRetry timer and remains in the Active state. OpenSent: BGP EVPN has sent an Open message to the peer and is now waiting for an Open message from the peer. If BGP EVPN receives a correct Open message, BGP EVPN enters the OpenConfirm state. If BGP EVPN receives an incorrect Open message, BGP EVPN sends a Notification message to the peer and enters the Idle state. If BGP EVPN receives a TCP connection teardown message, BGP EVPN resets the ConnectRetry timer and listens to the TCP connection initiated by the peer. BGP EVPN then enters the Active state. OpenConfirm: BGP EVPN is waiting for a Notification or Keepalive message. If BGP EVPN receives a Notification or TCP connection teardown message, BGP EVPN enters the Idle state. If BGP EVPN receives a Keepalive message, BGP EVPN enters the Established state. Established: Peers can exchange Update, Notification, and Keepalive messages. If BGP EVPN receives an Update or Keepalive message, BGP EVPN remains in the Established state. If BGP EVPN receives a Notification message, BGP EVPN enters the Idle state. 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	Status of the last BGP stage, which can be Idle, Connect, Active, OpenSent, OpenConfirm, Established or No neg.
BGP Peer Up count	Number of times the peer alternates between Up and Down.
Peer optional capabilities	Optional capabilities of the peer.
Peer Preferred Value	Preferred value of the peer.
Peer limit state	Suppression status of a channel for receiving packets sent by peers. true: The rate of the peer channel is limited. false: The rate of the peer channel is not limited.
remote AS	AS number of the peer.
Remote router ID	Router ID of the peer.
Update-group ID	Update group ID of the peer.
Received total routes	Number of route prefixes received.
Received active routes total	Number of active route prefixes received.
Received : Active Hold Time	Hold time of the peer.
Received	Number of messages received from the peer: Total: indicates the total number of messages received from the peer. Update messages: indicates the number of Update messages received from the peer. Open messages: indicates the number of Open messages received from the peer. KeepAlive messages: indicates the number of Keepalive messages received from the peer. Notification messages: indicates the number of Notification messages received from the peer. Refresh messages: indicates the number of route-refresh messages received from the peer.
Advertised total routes	Number of route prefixes sent.
Keepalive Time	Indicates the interval at which Keepalive messages are sent to the peer.
Negotiated: Active Hold Time	Hold time negotiated by peers.
4-byte-as capability has been enabled	4-byte AS capability enabled.
Sent	Number of messages sent to the peer: Total: indicates the total number of messages sent to the peer. Update messages: indicates the number of Update messages sent to the peer. Open messages: indicates the number of Open messages sent to the peer. KeepAlive messages: indicates the number of Keepalive messages sent to the peer. Notification messages: indicates the number of Notification messages sent to the peer. Refresh messages: indicates the number of route-refresh messages sent to the peer.
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.
No refresh received since peer has been configured	No Route-Refresh packets are received from the peer since the peer relationship is established.
No refresh sent since peer has been configured	No Route-Refresh packets are sent from the peer since the peer relationship is established.
No routing policy is configured	No routing policy has been configured.
Minimum route advertisement interval is 15 seconds	Minimum route advertisement interval: EBGP: 30s. IBGP: 15s.
Optional capabilities	Optional capabilities of the peer.
Route refresh capability has been enabled	Route-refresh enabled.
Connect-interface has been configured	Source interface for sending BGP packets specified.
Split group configured	Whether a split horizon group has been configured.
Pipe limit percent	Rate limit (in percentage) of a channel for receiving packets sent by peers.
Pipe limit count	Number of times rate limiting was performed for the channel to receive packets sent by peers.
Pipe last limit time	Last speed limit time of a channel for receiving packets sent by peers.
Routing policy configured	Whether a routing policy has been configured.
Type	BGP link type, which can only be IBGP link currently.
Port	Port number: Local: local port number, which is fixed at 179 because BGP uses TCP as the transport layer protocol. Remote: peer port number.
Configured	Timers that are locally configured: Active Hold Time: indicates the hold time. If BGP EVPN does not receive any Keepalive message from the peer in the hold time, BGP EVPN considers that the peer is Down. BGP EVPN then instructs the other peers to withdraw the routes received from this peer. Keep Alive Time: indicates the interval at which Keepalive messages are sent to the peer. Peers exchange Keepalive messages at intervals to show that they are working normally. Min Hold Time: specifies the minimum hold time. If the hold time configured on a remote device is less than the min-hold-value configured on the local device, no BGP peer relationship can be established between the two devices. However, if the hold time configured on the remote device is 0s, a BGP peer relationship can be established between the two devices. Connect-retry Time: specifies the ConnectRetry interval for a peer or peer group. When BGP initiates a TCP connection, the ConnectRetry timer is stopped if the TCP connection is established successfully. If the attempt to establish a TCP connection fails, BGP tries again to establish the TCP connection after the ConnectRetry timer expires.
