VMware NSX – Layer 2 VPN

Welcome back to the new blog, today we will be discussing about Layer 2 VPN functionality & support in NSX.

Key Points –

  1. As the name itself clarifies – Layer 2 VPN is used to stretch or extend Layer 2 networks across multiple sites on same broadcast domain.
  2. VPN connection is secured via route based IPSec tunnel across sites between L2VPN server & L2VPN Client, where L2VPN Client service runs at Source & L2VPN Server service runs at Target site.
  3. Extended network via L2VPN is single broadcast domain, so IPs of VM doesn’t get change when they are moved and gateway resides at source site only until you cutover to target site.
  4. VNI and VLAN backed both network types are supported for extension between source to target.
    • VLAN to VLAN supported.
    • VNI to VNI supported.
    • VLAN to VNI supported.
    • VNI to VLAN not a valid use case.
