L2 VPN setup

 

To set up a Layer 2 VPN (L2VPN) using Junos, you can follow these general steps:

1. Configure the Provider Edge (PE) Devices:

   • Set up the interfaces that will be used for the L2VPN connections.
   • Configure the routing instance for the L2VPN, typically using Virtual Switch Instance (VSI) or Bridge Domains.

2. Configure the Customer Edge (CE) Devices:

   • Set up the interfaces that will connect to the PE devices.
   • Configure the appropriate VLANs or other Layer 2 configurations on the CE devices.

3. Configure the Provider (P) Devices:

   • Set up the interfaces that will connect the PE devices.
   • Configure the necessary routing protocols and policies to ensure connectivity between the PE devices.

4. Configure the L2VPN:

   • Define the L2VPN instance on each PE device.
   • Specify the endpoints (PE devices) for the L2VPN.
   • Configure the L2VPN encapsulation type (such as Ethernet or VLAN).
   • Define the routing instances or bridge domains associated with the L2VPN.

5. Establish the L2VPN Connection:

   • Configure the appropriate routing protocols (such as BGP or LDP) to exchange VPN labels and reachability information between the PE devices.
   • Verify the L2VPN connection status and troubleshoot any connectivity issues.
