Configuring the Neighbor Interface for the Layer 2 Circuit

774
A Layer 2 circuit or pseudowire is a point-to-point Layer 2 connection transported by
means of MPLS or another tunneling technology on the service provider's network. Layer
2 circuits are also called pseudowires. A Layer 2 circuit is similar to a circuit cross-connect
(CCC), except that multiple Layer 2 circuits can be transported over a single
label-switched path (LSP) tunnel between two provider edge (PE) routers. In contrast,
each CCC requires a dedicated LSP.
The Junos OS implementation of Layer 2 circuits supports only the remote form of a
Layer 2 circuit; that is, a connection from a local customer edge (CE) router to a remote
CE router.

Each neighbor is identified by its IP address and is usually the end-point destination for
the label-switched path (LSP) tunnel transporting the Layer 2 circuit.
To configure a PE router as a neighbor for a Layer 2 circuit, specify the neighbor address
using the neighbor statement:
neighbor address {
...
}
You can include this statement at the following hierarchy levels:

edge (PE) router to the local customer edge (CE) router. This interface is tied to the
