MPLS L2VPNs

Introduction to MPLS L2VPNs

While working on MPLS L2VPNs, these are the topics that we need to be familiar with:

Different flavors of Layer 2 VPN

1. L2VPN (BGP-Signalled Pseudowires)
   • L2VPN Configuration and Troubleshooting
   • Site IDs
   • Label Base
   • Overprovisioning
   • Multihoming
   • VLAN Normalization
   • Traffic Policing
   • Out-of-band route reflection

2. L2Circuit (LDP singalled Pseudowires)

3. FEC 129 Psedowires
4. Virtual Private LAN Service (VPLS)
   • BGP-Sigaled VPLs
   • LDP-Signaled VPLS
   • FEC 129 VPLS
   • MAC Learning Modes in VPLS
   • MAC Limiting and Protection
   • Hub and Spoke VPLS
   • Multihomed sites in a VPLS
5. Ethernet VPN (EVPN)
   • Advantages of EVPN over MPLs
   • EVPN Route Types (2 and 3)
   • EVPN Single-homed
   • EVPN Multihoming
   • Automatic Gateway MAC-IP Sync
   • Host routes in L3VPNs
6. Inter-AS L2 VPNs
7. Circut Cross Connect
