Configuration Roadmap
The configuration roadmap is as follows:
1. Establish an MPLS L2VPN in SH-PW mode between CE1 and CE2.
2. Enable MPLS L2VPN and create VC connections on PE1 and PE2.
3. Configure the basic BFD capability and trigger the dynamic BFD for PW on PEs.
Data Preparation
To complete the configuration, you need the following data:
