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.
