Remote IP Address (bgpPeerRemoteAddr)

Remote IP address of this entry's BGP peer.

Peer Id (bgpPeerIdentifier)

BGP Identifier of this entry's BGP peer.

Peer State (bgpPeerState)

BGP peer connection state.

Desired State of Connection (bgpPeerAdminStatus)

Desired state of the BGP connection:

- A transition from "stop" to "start" will cause the BGP Start Event to be generated.
- A transition from "start" to "stop" will cause the BGP Stop Event to be generated.

This parameter can be used to restart BGP peer connections.

Note: Care should be used in providing write access to this object without adequate authentication.

Peer Negotiated Version (bgpPeerNegotiatedVersion)

Negotiated version of BGP running between the two peers.

Local IP Address (bgpPeerLocalAddr)

Local IP address of this entry's BGP connection.

Local Port (bgpPeerLocalPort)

Local port for the TCP connection between the BGP peers.

Remote Port (bgpPeerRemotePort)

Remote port for the TCP connection between the BGP peers. Note that the objects bgpPeerLocalAddr, bgpPeerLocalPort, bgpPeerRemoteAddr and bgpPeerRemotePort provide the appropriate reference to the standard MIB TCP connection table.

Remote AS (bgpPeerRemoteAs)

Remote autonomous system number.

Last Error (bgpPeerLastError)

Last error code and subcode seen by this peer on this connection. If no error has occurred, this field is zero. Otherwise, the first byte of this two byte octet string contains the error code, and the second byte contains the subcode.

Connect Retry Interval (bgpPeerConnectRetryInterval)

Time interval, in seconds, for the ConnectRetry timer. The suggested value for this timer is 120 seconds.

Hold Timer (bgpPeerHoldTime)

Time interval, in seconds, for the Hold Timer established with the peer. The value of this object is calculated by this BGP speaker using the smaller of either the value in bgpPeerHoldTimeConfigured or the Hold Time received in the OPEN message. The value of this object must be at lease three seconds unless it is zero, in which case the Hold Timer has not been established with the peer, or the value of bgpPeerHoldTimeConfigured is zero.

KeepAlive Timer (bgpPeerKeepAlive)

Time interval, in seconds, for the KeepAlive timer established with the peer. If the value of this object is zero, it indicates that either the KeepAlive timer has not been established with the peer, or the value of bgpPeerKeepAliveConfigured is zero.

Configured Hold Time (bgpPeerHoldTimeConfigured)

Time interval, in seconds, for the Hold Time configured for this BGP speaker with the peer. This value is placed in an OPEN message sent to the peer by this BGP speaker, and is compared with the Hold Time field in an OPEN message received from the peer when determining the Hold Time (bgpPeerHoldTime) with the peer. The value of this object must not be less than three seconds unless it is zero, in which case the Hold Time is NOT to be established with the peer.

The suggested value for this timer is 90 seconds.

Configured KeepAlive Time (bgpPeerKeepAliveConfigured)

Time interval, in seconds, for the KeepAlive timer configured for this BGP speaker with the peer. The value of this object only determines the KEEPALIVE messages' frequency relative to the value specified in bgpPeerHoldTimeConfigured. The actual time interval for KEEPALIVE messages is indicated by bgpPeerKeepAlive.

A reasonable maximum value for this timer is one third the value of bgpPeerHoldTimeConfigured. If the value of this object is zero, no periodical KEEPALIVE messages are sent to the peer after the BGP connection has been established.

The suggested value for this timer is 30 seconds.

MinASOrigination Interval (bgpPeerMinASOriginationInterval)

Time interval, in seconds, for the MinASOriginationInterval timer. The suggested value for this timer is 15 seconds.

MinRouteAdvertisement Interval (bgpPeerMinRouteAdvertisementInterval)

Time interval, in seconds, for the MinRouteAdvertisementInterval timer. The suggested value for this timer is 30 seconds.
