VPWS Supported Features

The JUNOSe software implementation of VPWS provides the following features:

• Support for the following types of network interfaces between the PE router and the CE device:
  • ATM with ATM Adaptation Layer 5 (AAL5) encapsulation
  • ATM with virtual channel connection (VCC) cell relay encapsulation
  • Cisco HDLC
  • Ethernet (Fast Ethernet, Gigabit Ethernet, 10-Gigabit Ethernet, Ethernet/VLAN)
  • Frame Relay
  • PPP
• Autodiscovery of L2VPN instance members using MP-BGP
• L2VPN signaling using MP-BGP to set up and tear down the pseudowires that constitute an L2VPN instance
• Multihoming
• Inter-AS option A, inter-AS option B, and inter-AS option C services

As with VPLS, VPWS does not support BGP multipaths.
