On which VLAN interface would an IP address typically be configured for a routed VLAN interface?

A routed VLAN interface is commonly configured on a VLAN interface, which is designated primarily for Layer 3 IP addressing. In Juniper Networks devices, these VLAN interfaces are identified as 'vlan.x' where 'x' corresponds to the VLAN ID. Therefore, configuring an IP address on a VLAN interface allows the router to perform routing functions for that specific VLAN.

In this context, the option indicating a VLAN interface, using the format 'vlan.100', reflects the standard convention in which IP addressing for a routed VLAN occurs. This interface acts as a gateway for devices within that VLAN, allowing them to communicate with other VLANs by routing packets through this interface.

Other options represent different interface types or structures which do not serve the same purpose as a routed VLAN interface. For instance, ge-0/0/20.100 suggests a sub-interface of an Ethernet interface, which is suitable for 802.1Q encapsulated traffic but not specifically for routing at the VLAN level. The rvi.100 format refers to a routing virtual interface, which is used in other architectures, and the ge-0/0/1 represents a physical Ethernet interface without specific VLAN association. None of these appropriately signifies a routed VLAN interface where an IP address is
