# VPLS Supported Features

The JUNOSe implementation of VPLS provides the following features:

- Single-level VPLS hierarchy within a single autonomous system (AS) using MPLS tunneling technology for the core
- Support for the following types of network interfaces between the PE router and the CE device:
  - Bridged Ethernet over ATM1483 subinterfaces
  - Fast Ethernet
  - Gigabit Ethernet
  - 10-Gigabit Ethernet
  - VLAN and S-VLAN subinterfaces over bridged Ethernet, Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interfaces
- Autodiscovery of VPLS instance members using MP-BGP
- VPLS signaling using MP-BGP to set up and tear down the pseudowires that constitute a VPLS instance
- VPLS signaling using LDP and the PWid FEC element (FEC Type 128) to set up and tear down the pseudowires that constitute a VPLS instance
- Interworking of the VPLS instance and the VPN routing and forwarding instance (VRF) using an external cable connection
- Multihoming
- Class of service (CoS)
- Inter-AS option A, inter-AS option B, and inter-AS option C services
- Minimal filtering and policing support

As with L2VPNs, VPLS does not support BGP multipaths.
