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 MX Series Ethernet Services Routers Layer 2 Configuration Guide discusses Layer 2 configurations on MX Series routers, including Layer 2 statement summaries and configuration statement examples. For more complete configuration examples, 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.
