Hello, friend!
The MA5608T supports MPLS services with VPLS. Note that only the SPUB board supports VPLS services.
Generally, you need to configure MPLS services before configuring VPLS.
As a combination of Ethernet and Multiprotocol Label Switching (MPLS) technologies, VPLS emulates all functions of the traditional local area network (LAN), with a purpose to connect multiple geographically isolated LANs that consist of Ethernet using the IP or MPLS network provided by carriers and make the LANs work as a LAN.
You can refer to the following configuration example:

Thanks!
