You are planning the configuration of Easy Virtual Networking (EVN).
Which of the following statements is true of an interface that will be an EVN trunk?
- It must support 802.1q encapsulation
- The interface can also be configured for VRF-Lite
- The interface will support OSPFv3
- The interface can support RIP
The interface must be able to support 802.1q encapsulation. The EVN trunk carries the traffic of multiple virtual routing and forwarding (VRF) instances, with the traffic of each instance tagged with an ID called the virtual network tag. Since the VLAN ID field of an 802.1q encapsulated packet is used for this ID, the link must be one that supports 802.1q.
Easy Virtual networking is a technology that allows for the creation of separate networks with separate routing tables and routing instances using the same physical topology. The IP addressing for the networks can even overlap with no problem. The networks are kept separate using the network ID tags in a similar fashion to the way switches keep VLANs separate by using VLAN tags.
An EVN trunk interface cannot also be configured for VRF-Lite. VRF-Lite is an earlier technology that accomplishes the same goal, but lacks the simplicity of EVN.
Neither RIP nor OSPFv3 is supported in Easy Virtual Networking EVN at all.
