Example: Configuring PBB with Single-Homed EVPN
This example shows how to integrate provider backbone bridging (PBB) with Ethernet VPN (EVPN). With this integration, the control plane operations in the core are simplified, providing faster convergence and scalability enhancements than regular EVPN. The PBB-EVPN applications include Data Center Interconnect (DCI) and carrier Ethernet E-LAN services.
Requirements
This example uses the following hardware and software components:
Three provider edge (PE) devices each connected to single-homed customer sites.
Four customer edge (CE) devices that are single-homed to the PE devices.
Junos OS Release 17.2R1 or later running on all the PE routers.
Before you begin:
Configure the device interfaces.
Configure an IGP, such as OSPF, on all the PE devices.
Establish an internal BGP session between the PE devices.
Enable RSVP on the PE devices.
Configure MPLS and label-switched paths (LSPs) between the PE devices.
Overview and Topology
Starting in Junos OS Release 17.2R1, PBB is integrated with Ethernet VPN (EVPN) to enable significant reduction in the control plane learning across the core, allowing a huge number of Layer 2 services, such as data center connectivity, to transit the network in a simplified manner.
In a PBB-EVPN network, the backbone core bridge (BCB) device in the PBB core is replaced with MPLS, while retaining the service scaling properties of the PBB backbone edge bridge (BEB). The B-component (provider routing instance) is signalled using EVPN BGP signaling and encapsulated inside MPLS using provider edge (PE) and provider (P) devices. Thus, PBB-EVPN combines the vast scaling property of PBB with the simplicity of a traditional basic MPLS core network, resulting in significant reduction in the amount of network-wide state information, as opposed to regular PBB.

EVPN
In Figure 1, PBB is integrated with EVPN, where the CE devices are single-homed to Devices PE1, PE2, and PE3.
