Which two statements are true regarding an RVI? (Choose two.)

A.
An RVI must be in an EX Series switch to enable routing between VLAN segments.

B.
An RVI does not require an IP address.

C.
An RVI is a Layer 3 logical interface.

D.
An RVI cannot coexist in an interface configuration if the switch performs Layer 2 operations.

Explanation:
routed VLAN interfaces
RVIs are similar to IRBs, SVIs, and BVIs. They can also be combined with other functions:

RVIs are similar to integrated routing and bridging (IRB) interfaces supported on Juniper
routers and switch virtual interfaces (SVIs) and bridge-group virtual interfaces (BVIs)
supported on other vendors devices.
VRF is often used in conjunction with Layer 3 subinterfaces, allowing traffic on a single
physical interface to be differentiated and associated with multiple virtual routers. For
more information about VRF, see Understanding Virtual Routing Instances on EX
Series Switches on page 26.
For redundancy, you can combine an RVI with implementations of the Virtual Router
Redundancy Protocol (VRRP) in both bridging and virtual private LAN service (VPLS)
environments. For more information about VRRP, see Understanding VRRP on EX
Series Switches.

Purpose

Determine status information and traffic statistics for routed VLAN interfaces (RVIs) by using the following commands:

Action

Display RVI interfaces and their current states:
user@switch> show interfaces vlan terse

Interface Admin Link Proto Local Remote
vlan up up
vlan.111 up up inet 111.111.111.1/24

Display Layer 2 VLANs, including any tags assigned to the VLANs and the interfaces associated with the VLANs:
user@switch> show vlans

Name Tag Interfaces
default
None
employee-vlan 20
ge-1/0/0.0, ge-1/0/1.0, ge-1/0/2.0
marketing 40
ge-1/0/10.0, ge-1/0/20.0, ge-1/0/30.0
support 111
ge-0/0/18.0

Display Ethernet switching table entries for the VLAN that is attached to the RVI:

user@switch> show ethernet-switching table

Ethernet-switching table: 1 entries, 0 learned
VLAN MAC address Type Age Interfaces
support 00:19:e2:50:95:a0 Static – Router

Display an RVIs ingress-counting statistics with either the show interfaces vlan detail command or the show interfaces vlan extensive command. Ingress counting is displayed as Input bytes and Input packets under Transit Statistics.

user@switch> show interfaces vlan.100 detail

Meaning

show interfaces vlan displays a list of interfaces, including RVI interfaces, and their current states (up, down).
show vlans displays a list of VLANs, including any tags assigned to the VLANs and the interfaces associated with the VLANs.
show ethernet-switching table displays the Ethernet switching table entries, including VLANs attached to the RVI.
show interfaces vlan detail displays RVI ingress counting as Input Bytes and Input Packets under Transit Statistics.
