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.
