Layer 2 VPN in Service Provider

Layer 2 VPN Model

AToM supports the following Layer 2 technologies over MPLS:

• Ethernet

• 802.1Q VLAN

• ATM AAL5 frames

• ATM cells

• Frame Relay

• PPP

• HDLC

Here Some example notes of :

• Implementing AToM for like to like circuits

• Implementing AToM for any to any circuits

• Local switching
