VPWS applies for all services, including Ethernet, ATM, Frame Relay, etc. These tunnels can either be specific to a particular VPWS, or be shared among several services.
Layer 2 circuits are then mapped onto tunnels in the SP network. PE devices act as Layer 2 circuit switches. The PE devices provide a logical interconnect such that a pair of CE devices appears to be connected by a single logical Layer 2 circuit. L2VPN, also known as a pseudowire, is defined in RFC4665, where they are called Virtual Private Wire Service (VPWS):
This post will over note how to configure L2VPN with Junos ?
As we have a MPLS enabled network, it was decided that would be the easiest way to get their POC up and running quickly, as we were under a bit of a hard deadline!įor me, it was good little project, even though I know what L2VPNs were and how they work, I had never configured one myself. As this circuit is being using as a POC (for now), it was agreed that a Layer 2 VPN (L2VPN/pseudowire) will be best suited, because a simple point-to-point connection was needed between two PEs. With that being said, I’ve been given a wee project to provision a circuit for a business customer between two sites for a Proof Of Concept. It has been a busy few weeks trying to stay ahead of all the new work that has been coming towards myself and the team, due to the in sourcing of the core network! Lucky enough for my team, we have finally got our hands onto full end-to-end connectivity! Fun times ?
