show bgp l2vpn evpn summary
Use this command to display a summary of BGP EVPN neighbor status.
Command Syntax
show bgp l2vpn evpn summary
Parameters
None
Command Mode
Exec mode
Applicability
This command was introduced before OcNOS version 1.3.
Example
#show bgp l2vpn evpn summary
BGP router identifier 1.1.1.1, local AS number 100
BGP table version is 17
1 BGP AS-PATH entries
0 BGP community entries

Total number of Established sessions 3
The start of the output shows:
• The BGP router identifier and the local router AS number.
• The BGP table version tracks the local BGP table version. Any time the BGP best path algorithm executes, the table version increments.
• BGP AS-PATH entry and community entries.
Table 1-4 explains the fields for each neighbor entry.
 
Table 1-4: neighbor fields 
Field
Description
Neighbor
IP address of peer.
V
BGP version of peer.
AS
Autonomous system number of peer.
MsgRcvd
Messages received since the BGP connection was established.
MsgSent
Messages sent since the BGP connection was established.
TblVer
Last version of the local router’s BGP database advertised to the peer.
InQ
Received messages waiting in the input queue for further processing.
OutQ
Messages waiting in the output queue to be sent.
Up/Down
Connection up time in the interface.
State/PfxRcd
If the TCP session is up and the BGP peers have formed an adjacency, this field shows how many prefixes have been received from the remote neighbor.
 
Other states:
 
Idle: The local router has not allocated resources for the peer connection, so incoming connection requests are refused
 
Idle (Admin): The peer has shut down
 
Idle (PfxCt): Prefix overflow
 
Idle (G-shut): Graceful shutdown
 
Connect: BGP is waiting for the TCP connection to complete
 
Active: the local router is trying to establish a TCP connection to the remote peer. You might see this if the local peer has been configured, but the remote peer is unreachable or has not been configured.
 
OpenSent: BGP is waiting for an open message from its peer
 
OpenConfirm: BGP received an open message from the peer and is now waiting for a keepalive or notification message. If BGP receives a keep alive message from the peer, the state changes to established. If the message is a notification, the state changes to idle.
 
Established: BGP is ready to exchange update, notification, and keep alive messages with its peer
 
Invalid: The session state is invalid.
AD
Number of EVPN type 1 Ethernet Auto-discovery routes: Only originated for multi-homed sites. Type 1 routes allow fast convergence where PE devices can change the next-hop adjacencies for all MAC addresses associated with a particular Ethernet Segment and aliasing where traffic can be balanced across multiple egress points
MACIP
Number of EVPN type 2 MAC/IP routes: Endpoint reachability information, including MAC and IP addresses of the endpoints.
MCAST
Number of EVPN type 3 Inclusive Multicast routes: Broadcast, Unknown Unicast and Multicast (BUM) traffic.
ESI
Number of EVPN type 4 Ethernet Segment Routes: Used in multi-homing for Designated Forwarder Election. The Designated Forwarder sends BUM traffic to the CE on a particular Ethernet Segment.
