The BGP External Setting serves two purposes:

  • Provides a means of testing the BGP endpoint instrumentation and analysis functionality of Network Protocol Manager for BGP.

  • Provides a means for Network Protocol Manager for BGP to import BGP endpoint status updates from an adapter, such as the Adapter for Alcatel-Lucent 5620 SAM EMS.

    BGP External Setting parameters and their values lists the BGP External Setting parameters.

Description

AnalysisMode

ENABLEDDISABLED

Default: ENABLED

Enables or disables the availability analysis of the BGP endpoint (BGPProtocolEndpoint) data collected from an external source.

PeerState

UNKNOWNIDLECONNECTACTIVEOPENSENTOPENCONFIRMESTABLISHED

Default: ESTABLISHED

Determines the initial peer state for the stored instrumentation objects that represent BGPProtocolEndpoints.

  • UNKNOWN is the default PeerState value before Network Protocol Manager for BGP sends SNMP polls to the device that is hosting the BGP endpoint.

  • IDLE indicates that the BGP service for the BGP endpoint refuses all incoming BGP connections. No resources are allocated to the peer.

  • CONNECT indicates that the BGP service for the BGP endpoint is waiting for the transport protocol connection to be completed.

  • ACTIVE indicates that the BGP service for the BGP endpoint is trying to acquire a peer by initiating a transport protocol connection.

  • OPENSENT indicates that the BGP service for the BGP endpoint is waiting for an OPEN message from its peer. When an OPEN message is received, the BGP service checks all fields for correctness.

  • OPENCONFIRM indicates that the BGP service for the BGP endpoint is waiting for a KEEPALIVE or NOTIFICATION message. If the host device receives a KEEPALIVE message, the BGP service changes the state to Established.

  • ESTABLISHED indicates that the BGP service for the BGP endpoint can exchange UPDATE, NOTIFICATION, and KEEPALIVE messages with its peer.
