I'm trying to understand what kind of L2 VPN's and L3 VPN's there are, and what there advantages are over the other
I'm hearing and seeing a lot of variants on the internet and I'm trying to keep them seperate as it's getting confusing. Can someone help met with the 2 list and if possibe explain what the differences are.
I have made the following list for L2 VPN's and L3 VPN's
L2VPN:
MPLS L2 VPN Using VPWS (Point-to-Point):
- Virtual Leased Line (VLL) in CCC Mode
- VLL in SVC Mode
- VLL in Martini Mode (PWE3)/ EoMPLS
- VLL in Kompella Mode
MPLS L2 VPN Using VPWS (Point-to-multipoint):
- Virtual Private LAN Service (VPLS)
Other types of L2VPN:
- 802.1q Tunneling
- E-VPN - This seems to be the future (http://blogs.cisco.com/tag/e-vpn/).
- Frame Relay (Old)
- ATM (Old)
L3VPN:
- IPSEC - Point to Point
- MPLS/BGP L3 VPN
