Root-cause problems diagnosed by MPLS Manager lists the root-cause problems that are diagnosed by MPLS Manager.

Table 1. Root-cause problems diagnosed by MPLS Manager

Managed object

Root cause

Condition

LSP

Down

For a TE tunnel, the LSP is operationally down because it failed to establish one or more TE LSPs.

For a TE LSP or subLSP, the LSP is operationally down because one of its LSP hops has failed.

For an LDP LSP, the LSP is operationally down because the LSP outsegment of the LSP’s source device has failed.

LdpAdjacency

Down

The LdpAdjacency is operationally down because at least one of its LdpProtocolEndpoints has failed.

RsvpSession

Down

The RsvpSession is operationally down because at least one of its RsvpProtocolEndpoints has failed.

Forwarder

Down

The Forwarder is operationally down because it has no ForwarderEndpoint or all of its ForwarderEndpoints have failed.

PseudoWire

Down

The PseudoWire is operationally down because at least one of its ForwarderEndpoints or underlying LSPs has failed.

VRF

Down

The VRF is operationally down due to one of the following conditions:

  • VRF has no associated interfaces.

  • VRF has one or more associated interfaces and all of them have failed.

BGPService

Down

The BGP service is down, and all the BGP sessions that are associated with the service are down.

BGPProtocolEndpoint

Disabled

The BGP protocol endpoint or its associated physical interface is administratively down (manually disabled), and the BGP session for this endpoint is reporting an improper state.

IBGPPeerMissing

The interior BGP (iBGP) peer (remote iBGP service) for this endpoint is not present in the topology, and the BGP session for this endpoint is reporting an improper state.

RemoteAsMismatch

The actual autonomous system (AS) number and the locally configured AS number of the BGP peer (remote BGP service) for this endpoint do not match, and the BGP session for this endpoint is reporting an improper state.

RemoteSpeakerNot-Configured

The BGP peer for this endpoint is not configured to speak BGP to the endpoint, and the BGP session for this endpoint is reporting an improper state.

RemoteSystemNot-RunningBGP

The BGP peer for this endpoint does not run BGP, and the BGP session for this endpoint is reporting an improper state.

BGPSession

Down

The BGP session is not established, and no other known problem can explain why this session is not established.
