Local—Address of the local router. The address is followed by the peer's port number.

Type—Type of peer: Internal or External.

State—Current state of the BGP session:

Active—BGP is initiating a transport protocol connection in an attempt to connect to a peer. If the connection is successful, BGP sends an open message.

Connect—BGP is waiting for the transport protocol connection to complete.

Established—The BGP session has been established, and the peers are exchanging update messages.

Idle—This is the first stage of a connection. BGP is waiting for a Start event.

OpenConfirm—BGP has acknowledged receipt of an open message from the peer and is waiting to receive a keepalive or notification message.

OpenSent—BGP has sent an open message and is waiting to receive an open message from the peer.

Flags—Internal BGP flags:

Aggregate Label—BGP has aggregated a set of incoming labels (labels received from the peer) into a single forwarding label.

CleanUp—The peer session is being shut down.

Delete—This peer has been deleted.

Idled—This peer has been permanently idled.

Initializing—The peer session is initializing.

SendRtn—Messages are being sent to the peer.

Sync—This peer is synchronized with the rest of the peer-group.

Unconfigured—This peer is not configured.

WriteFailed—An attempt to write to this peer failed.

Last State—Previous state of the BGP session.

Last Event—Last activity that occurred in the BGP session:

Closed—The BGP session closed.

ConnectRetry—The transport protocol connection failed, and BGP is trying again to connect.

HoldTime—The session ended because the hold timer expired.

KeepAlive—The local router sent a BGP keepalive message to the peer.

Open—The local router sent a BGP open message to the peer.

OpenFail—The local router did not receive an acknowledgment of a BGP open message from the peer.

RecvKeepAlive—The local router received a BGP keepalive message from the peer.

RecvNotify—The local router received a BGP notification message from the peer.

RecvOpen—The local router received a BGP open message from the peer.

RecvUpdate—The local router received a BGP update message from the peer.

Start—The peering session started.

Stop—The peering session stopped.

TransportError—A TCP error occurred.

Last Error—Last error that occurred in the BGP session:

Cease—An error occurred, such as a version mismatch, that caused the session to close.

Finite State Machine Error—In setting up the session, BGP received a message that it did not understand.

Hold Time Expired—The session's hold time expired.

Message Header Error—The header of a BGP message was malformed.

Open Message Error—A BGP open message contained an error.

None—No errors occurred in the BGP session.

Update Message Error—A BGP update message contained an error.

Export—Name of the export policy that is configured on the peer.

Import—Name of the import policy that is configured on the peer.

Options—Configured BGP options:

Restart time requested by this peer—Restart time requested by this neighbor during capability negotiation.

Restart flag received from the peer—When this field appears, the BGP speaker has restarted (Restarting) and this peer should not wait for the end-of-rib marker from the speaker before advertising routing information to the speaker.

NLRI that peer supports restart for—Address families indicates graceful restart during capability negotiation.

NLRI that restart is negotiated for—Both address families are supported by both this peer and its neighbor.

NLRI of received end-of-rib markers—Address families for which end-of-routing-table markers are received from the neighbor.

NLRI of all end-of-rib markers sent—Address families for which end-of-routing-table markers are sent to the neighbor.

Table inet.number—Information about the routing table.

RIB State—BGP is in the graceful restart process for this routing table: restart is complete or restart in progress.

Bit—Number that represents the entry in the routing table for this peer.

Send state—State of the BGP group: in sync, not in sync, or not advertising.

Active prefixes—Number of prefixes received from the peer that are active in the routing table.

Received prefixes—Total number of prefixes from the peer, both active and inactive, that are in the routing table.

Suppressed due to damping—Number of routes currently inactive because of damping or other reasons. These routes do not appear in the forwarding table and are not exported by routing protocols.

Last traffic (seconds)—Last time any traffic was received from the peer or sent to the peer, and the last time the local router checked.

Input messages—Messages that BGP has received from the receive socket buffer, showing the total number of messages, number of update messages, and the buffer size in octets. The buffer size is 16 KB.

Output messages—Messages that BGP has written to the transmit socket buffer, showing the total number of messages, number of update messages, and the buffer size in octets. The buffer size is 16 KB.

Output queue[0], Output queue[1]—Number of BGP packets that are queued to be transmitted to a particular neighbor for a particular routing table. Output queue 0 is for unicast NLRIs, and queue 1 is for multicast NLRIs.
