The benefits of CISCO-BGP-MIB are as follows:

• MIB objects and SNMP notifications can keep track of prefix counters and capabilities related to BGP sessions.

• The following address families are supported: IPv4, IPv6, VPNv4, VPNv6.

• New traps are added to CISCO-BGP4-MIB that allow data to be returned for both IPv4 and IPv6 peers.

Cisco BGP Peer Table—cbgpPeer2Table

This table is an augmentation of the former Cisco BGP Peer Table, with flexible indexing to support both IPv4 and IPv6. This table contains one entry per BGP peer about the connections with BGP peers. MIB objects in this table are:

• cbgpPeer2Type

• cbgpPeer2RemoteAddr

• cbgpPeer2State

• cbgpPeer2AdminStatus

• cbgpPeer2NegotiatedVersion

• cbgpPeer2LocalAddr

• cbgpPeer2LocalPort

• cbgpPeer2LocalAs

• cbgpPeer2LocalIdentifier

• cbgpPeer2RemotePort

• cbgpPeer2RemoteAS

• cbgpPeer2RemoteIdentifier

• cbgpPeer2InUpdates

• cbgpPeer2OutUpdates

• cbgpPeer2InTotalMessages

• cbgpPeer2OutTotalMessages

• cbgpPeer2FsmEstablishedTransitions

• cbgpPeer2FsmEstablishedTime

• cbgpPeer2ConnectRetryInterval

• cbgpPeer2HoldTime

• cbgpPeer2KeepAlive

• cbgpPeer2HoldTimeConfigured

• cbgpPeer2KeepAliveConfigured

• cbgpPeer2MinAsOriginationInterval

• cbgpPeer2MinRouteAdvertisementInterval

• cbgpPeer2InUpdateElapsedTime

• cbgpPeer2LastErrorTxt

• cbgpPeer2PrevState

BGP Session Capability Table—cbgpPeer2CapsTable

This table is an augmentation of the former Cisco BGP Session Capability Table, with flexible indexing to support both IPv4 and IPv6. BGP sessions can have multiple capabilities, which are sent to the peer in BGP OPEN messages. BGP_CAP_TYPE_AS4 is the only new capability support added from the previous version of cbgpPeerCapsTable. This table contains an entry corresponding to a capability code and an index. The MIB object in this table is:

• cbgpPeer2CapCode

Peer Address Family Table—cbgpPeer2AddrFamilyTable

This table is an augmentation of the former Cisco Peer Address Family Table, with flexible indexing to support both IPv4 and IPv6. This table contains supported address families. Only the following address families are supported: IPv4, VPNv4, IPv6, and VPNv6. Output is similar to the original MIB Object Identifier (OID): cbgpPeerAddrFamilyTable. The MIB object in this table is:

• cbgpPeer2AddrFamilyName

Prefix CounterTable—cbgpPeer2AddrFamilyPrefixTable

This table is an augmentation of the former Cisco Prefix Counter Table, with flexible indexing to support both IPv4 and IPv6. This table contains per peer route prefix counters for all of the supported address families. Only the following address families are supported: IPv4, VPNv4, IPv6, and VPNv6. Output is similar to the original MIB OID: cbgpPeerAddrFamilyPrefixTable. The MIB objects in this table are:

• cbgpPeer2AcceptedPrefixes

• cbgpPeer2DeniedPrefixes

• cbgpPeer2PrefixAdminLimit

• cbgpPeer2PrefixThreshold

• cbgpPeer2PrefixClearThreshold

• cbgpPeer2AdvertisedPrefixes

• cbgpPeer2SuppressedPrefixes

• cbgpPeer2WithdrawnPrefixes

cbgpNotifsEnable

This global object contains information about which traps are enabled. When the snmp-server enable traps bgp cbgp2 command is configured, the following traps are sent:

cbgpPeer2FsmStateChange

This notification is an augmentation of the former FSM State Change Notification, with support for IPv6. This notification contains the following MIB objects:

• cbgpPeer2LastError

• cbgpPeer2State

• cbgpPeer2LastErrorTxt

• cbgpPeer2PrevState

cbgpPeer2BackwardTransition

This notification is an augmentation of the former Backward Transition Notification, with support for IPv6. This is sent when BGP FSM moves from a higher numbered state to a lower numbered state. This notification contains the following MIB objects:

• cbgpPeer2LastError

• cbgpPeer2State

• cbgpPeer2LastErrorTxt

• cbgpPeer2PrevState

cbgpPeer2PrefixThresholdExceeded

This notification is an augmentation of the former Prefix Threshold Exceeded Notification, with support for IPv6. This is sent when the prefix count for an address family on a BGP session exceeds the configured threshold value. This notification contains the following MIB objects:

• cbgpPeer2PrefixAdminLimit

• cbgpPeer2PrefixThreshold

cbgpPeer2PrefixThresholdClear

This notification is an augmentation of the former Prefix Threshold Clear Notification, with support for IPv6. It is sent when the prefix count drops below the clear trap limit for an address family on a BGP session after the generation of cbgpPeer2PrefixThresholdExceeded notification. This notification contains the following MIB objects:

• cbgpPeer2PrefixAdminLimit

• cbgpPeer2PrefixClearThreshold

cbgpPeer2BackwardTransNotification

This notification is generated when the BGP FSM moves from a higher numbered state to a lower numbered state. It contains the following MIB objects:

• cbgpPeer2LastError

• cbgpPeer2State

• cbgpPeer2LastErrorTxt

• cbgpPeer2PrevState

cbgpPeer2EstablishedNotification

This notification is generated when the BGP FSM enters the established state. The MIB objects are:

• cbgpPeer2LastError

• cbgpPeer2State

cbgpPeer2BackwardTransNotification

This notification is generated when the BGP FSM moves from a higher numbered state to a lower numbered state. The MIB objects are:

• cbgpPeer2LastError

• cbgpPeer2State

cbgpPeer2FsmStateChange

This notification is generated for every BGP FSM state change. The MIB objects are:

• cbgpPeer2LastError

• cbgpPeer2State

• cbgpPeer2LastErrorTxt

• cbgpPeer2PrevState

cbgpPeer2BackwardTransition

This notification is generated when the BGP FSM moves from a higher numbered state to a lower numbered state. The MIB objects are:

• cbgpPeer2LastError

• cbgpPeer2State

• cbgpPeer2LastErrorTxt

• cbgpPeer2PrevState

cbgpPeer2PrefixThresholdExceeded

This notification is generated when the prefix count exceeds the configured warning threshold on a session for an address family. The MIB objects are:

cbgpPeer2PrefixThresholdClear

This notification is generated when the prefix count drops below the configured clear threshold on a session for an address family once cbgpPeer2PrefixThresholdExceeded is generated. This notification is not generated if the peer session goes down after the generation of cbgpPrefixThresholdExceeded. The MIB objects are:

• cbgpPeer2PrefixAdminLimit

• cbgpPeer2PrefixClearThreshold
