Configuring J Series Services Router Switching Interfaces
The J Series routers with multiport Gigabit Ethernet uPIMs supports Ethernet access
switching. This functionality provides the ability to switch traffic at Layer 2 in addition
to routing traffic at Layer 3.
J Series routers with multiport Gigabit Ethernet uPIMs can be deployed in branch
offices as an access or desktop switch with integrated routing capability. The multiport
Gigabit Ethernet uPIM provides Ethernet switching, while the Routing Engine provides
routing functionality.
Routed traffic is forwarded from any port of the multiport Gigabit Ethernet uPIM to
the WAN interface. Switched traffic is forwarded from one port of the multiport
Gigabit Ethernet uPIM to another port on the same the multiport Gigabit Ethernet
uPIM. Switched traffic is not forwarded from a port on one multiport Gigabit Ethernet
uPIM to a port on a different multiport Gigabit Ethernet uPIM. For more information
about configuring the multiport Gigabit Ethernet uPIM switching mode, see the JUNOS
System Basics Configuration Guide.
In access switching mode, only one physical interface is configured for the entire
multiport Gigabit Ethernet uPIM. The single physical interface serves as a Virtual
Router Interface (VRI). Configuration of the physical port characteristics is done under
the single physical interface.
