What are two characteristics of routed ports on a multilayer switch?

• A. They are associated with a VLAN and used for inter-VLAN communication
• B. They are mostly configured between switches at the core and distribution layers and are not linked to a VLAN
• C. They cannot be used for routing protocols
• D. They support Layer 2 switching only

Answer: (B)

Routed ports on a multilayer switch are indeed not associated with any VLAN. This characteristic allows them to function as Layer 3 interfaces, handling traffic at the network layer instead of being tied to a specific VLAN like regular switch ports. Because routed ports do not belong to a VLAN, they can facilitate routing between different networks, which is essential for interconnecting disparate IP subnets or networks. These ports are typically employed in scenarios that require direct communication between different networks, making them especially prevalent in the core and distribution layers of network architecture. In these layers, routed ports provide the flexibility and performance necessary for managing traffic efficiently without the overhead of VLAN tagging. This enables multilayer switches to perform routing functions, while traditional access ports support Layer 2 switching. Thus, the designation of routed ports is integral for Layer 3 routing capabilities on switches.
