z
Share mesh protection: This protection mode is designed for saving bandwidth in
the mesh network topology. In short, an LSP is used as the secondary LSP for
multiple LSPs. When any LSP fails, data packets to be transported over the LSP
are switched to the secondary LSP. The triggering and switching mechanisms of
this mode are similar to 1:1 protection.
z
Packet 1+1 protection: This protection mode is similar to 1+1 protection. The
difference between them is that for packet 1+1 protection, the ingress node sends
packets with order labels through the primary LSP and the secondary LSP to the
egress node. For the packets with the same order label, the egress node receives
the one arrived in advance and drops the other. This protection mode is rather
complex and difficult to control.
Now, only 1:1 protection is supported.

I. Configuration Prerequisites
1) Application
environment
MPLS OAM basic verification capability is designed to monitor the connectivity state of
an MPLS network, and verify and pinpoint the defects in the MPLS network. To verify
the connectivity of the MPLS network, you should configure the MPLS OAM function for
LSPs.
2) Configuration
preparation
To configure MPLS OAM basic capability, perform the following tasks:
