Usage Guidelines

Configuring BGP peer groups simplifies BGP network configuration and improves the route advertisement efficiency.

The display bgp group command displays the information about the peer group, including information about the peers in the peer group and configuration information about the peer group. This command is used in the following scenarios:

Verify the configuration after running the group command to configure a peer group.
Verify the configuration after running the peer group command to add a peer to the peer group.
Verify the configuration after running the undo peer group command to delete a peer from a peer group.
Verify the configuration after modifying the configuration of a peer group.

**Table 1** Description of the **display bgp evpn group** command output
Item	Description
BGP peer-group	Name of a BGP peer-group

Minimum route advertisement interval	Minimum interval between route advertisements
PeerSession Members	Peers that set up sessions
Peer Preferred Value	Preferred value of a peer
Peer Members	Indicating that the following information is about peers
Peer	IP address of a peer
V	BGP version
As	Number of the AS where a member of a peer group resides
MsgRcvd	Number of received messages
MsgSent	Number of sent messages
OutQ	Number of messages to be sent to peers
Up/Down	Period of time during which a BGP session keeps the current state
State	BGP state mechanism: 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 to the remote BGP peer, starts the ConnectRetry Timer with the initial value, detects a TCP connection initiated by the remote BGP peer, and changes its state to Connect. Idle(Admin): indicates that the peer relationship is shut down inactively and no attempt is made to establish the neighbor relationship. If the peer ignore command is configured or the peer is set to the Down state through the MIB, the neighbor is in the Idle (Admin) state. Idle(Ovlmt): indicates that the peer relationship is interrupted because the number of routes exceeds the upper threshold. After a BGP peer relationship is interrupted due to the running of the peer route-limit command, the status of the BGP peer relationship is displayed as Idle(Ovlmt). If the reset bgp command is not run, the BGP peer relationship will not be reestablished. Connect: indicates that BGP waits 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 detect a TCP connection 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 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 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 waits 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 detect a TCP connection initiated by the remote peer, and changes its state to Active. OpenConfirm: indicates that BGP waits for a Notification message or a 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 packets. 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.
PrefRcv	Indicates the number of route prefixes received by the local peer from the remote peer.
