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
