L2VPN Supported Features

The JUNOSe software implementation of L2VPNs 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
• Inter-AS option A, inter-AS option B, and inter-AS option C services

As with VPLS, L2VPNs do not support BGP multipaths.
