Layer 2 and Layer 3 Features on MX Series Routers
You can configure MX Series routers to provide simultaneous support for Layer 2 and Layer 3 Ethernet services. In many cases, Layer 2 protocols run on some interfaces, and Layer 3 protocols run on others.
The Junos Layer 2 Configuration Guide discusses Layer 2 configurations on supported routers, including Layer 2 statement summaries and configuration statement examples. For more complete Layer 2 configuration examples for MX Series routers, see the Junos MX Series Ethernet Services Routers Solutions Guide.
For more information about configuring Layer 3 features and functions (such as class of service), see the relevant Junos configuration guides.
