This section describes how to configure MPLS OAM to check the connectivity of a static bidirectional co-routed LSP.
Static bidirectional co-routed LSPs are used to build a next-generation packet switched (PS) transport network, which is similar to an optical transport network (OTN) in the aspects of service bearing and OAM. Since traditional transport networks (such as SDH and OTN networks) set high benchmarks for reliability and maintenance, static bidirectional co-routed LSPs must provide powerful OAM capabilities.
MPLS OAM can check the connectivity of a static bidirectional co-routed LSP and supports multiple detection intervals. If MPLS OAM detects a fault on a static bidirectional co-routed LSP, it triggers a traffic switchover to prevent traffic loss.
Before configuring MPLS OAM for a bidirectional co-routed LSP, configure the bidirectional co-routed LSP.
