Usage Guidelines

Usage Scenario

To check the following information about BGP EVPN peers, run the display bgp evpn peer command:

Status of connections between BGP EVPN peers
Configuration information about BGP EVPN peers
Whether BGP EVPN peers are successfully configured using the peer enable command
Whether BGP EVPN peers are successfully deleted using the undo peer enable command
To check information about slow BGP EVPN peers, run the display bgp evpn slow-peer command. The information includes the time when a peer began to be identified as a slow peer, the time when a peer last exited from the slow peer state, the number of times a peer has been identified as a slow peer, and the remaining time for a peer to exit from the slow peer state.

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 evpn peer** command output
Item	Description
Total number of peers	Number of peers.
Switchback detection timer	Remaining time for a peer to exit from the slow peer state.
Peer	IP address of a peer.
LastSlowEndTime	Time when a peer last exited from the slow peer state.
SlowStartTime	Time when a peer began to be identified as a slow peer.
SlowCount	Number of times a peer has been identified as a slow peer.
BGP local router ID	Local BGP EVPN router ID.
Local AS number	Local AS number.
AS	Autonomous system number.
Peers in established state	Number of peers in the Established state.
V	BGP version of a peer.
MsgRcvd	Number of messages received.
MsgSent	Number of messages sent.
OutQ	Number of messages to be sent to a peer.
Up/Down	Duration in which the BGP EVPN session remains in the current state.
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.
PrefRcv	Number of route prefixes received from a peer.
