MPLS_LSPM_1.3.6.1.4.1.2011.5.25.121.2.1.81 hwMplsTunnelBfdPathMismatch

Trap Buffer Description

The forward primary LSP path is the same as the reverse hot-standby LSP path, and the reverse primary LSP path is the same as the forward hot-standby LSP path, causing path mismatches.(Local: SessionTunnelId=[LocalSessionTunnelId], LocalLspId=[LocalLocalLspId], IngressLsrId=[LocalIngressLsrId], EgressLsrId=[LocalEgressLsrId], TunnelName=[LocalTunnelName]. Peer: SessionTunnelId=[PeerSessionTunnelId], LocalLspId=[PeerLocalLspId], IngressLsrId=[PeerIngressLsrId], EgressLsrId=[PeerEgressLsrId], TunnelName=[PeerTunnelName]. LocalSignalledTunnelName=[LocalSignalledTunnelName])

An path connection was incorrect. The forward primary path overlapped the reverse backup path, or the reverse primary path overlapped the forward backup path.

Impact on the System

If a link fails, the forward and reverse BFD sessions go Down, and services on the LSP are interrupted.

Possible Causes

  • Cause 1:

    An incorrect path connection occurred.

    The forward primary path overlapped the reverse backup path or the reverse primary path overlapped the forward backup path.

  • Cause 2:

    An incorrect path connection occurred.

    The forward primary path overlapped the reverse backup path or the reverse primary path overlapped the forward backup path.

Procedure

  • Correctly plan tunnel paths so that the forward primary path overlaps the reverse primary path, or the reverse backup path overlapped the forward backup path.
