Junos Platform for Provider Bridging

B

Provider bridging is a networking technology that enables service providers to connect customer networks over a provider's infrastructure while maintaining customer VLAN (Virtual Local Area Network) separation. The technology works by mapping customer VLANs to provider VLANs, and transporting customer traffic over provider VLANs.

Among the Junos platform devices listed in the question, MX Series devices support provider bridging. The MX Series is a high-performance, carrier-grade routing platform designed to deliver a range of services, including routing, switching, security, and service aggregation.

MX Series devices support a variety of Layer 2 and Layer 3 VPN technologies, including provider bridging, which is implemented using the IEEE 802.1ad standard, also known as QinQ. QinQ allows multiple customer VLANs to be transported over a single provider VLAN, with each customer VLAN identified by a unique VLAN ID.

Provider bridging on MX Series devices can be configured using either the Junos CLI (Command Line Interface) or the Junos Space Network Management Platform. The configuration involves creating provider VLANs, mapping customer VLANs to provider VLANs, and configuring the interfaces that connect to the customer and provider networks.

In summary, the correct answer to the question is C - MX Series devices support provider bridging.
