Refer to the exhibit.
Click the Exhibit button.
You have an EVI implemented between PE-1, PE-2, and PE-3 to allow communication between CE-1 and CE-2. CE-2 receives unicast traffic from CE-1 on both links to PE-2 and
PE-3. When CE-1 sends broadcast traffic, CE-2 receives it on only one of the multihomed links.
Referring to the exhibit, which EVPN route type enables this behavior?
Suggested Answer: B, C

This is an EVPN Type-2 route, also called a MAC/IP advertisement route, that is used to advertise host IP and MAC address information to other VTEPs in an EVPN network. The route type field in the EVPN NLRI has a value of 2, indicating a Type-2 route. The device advertising this route into EVPN is 192.168.101.5, which is the IP address of the VTEP that learned the host information from the local CE device. This IP address is carried in the MPLS label field of the route as part of the VXLAN encapsulation.

Are we sure about that? I feel like it could be Type 2 too.

Totally agree, Type 4 makes the most sense here.

Wait, so CE-2 only gets broadcasts on one link? That's odd!

I thought it was Type 3? Seems like a tricky one.

It's definitely Type 4 for this scenario.

I recall that Type 1 is for Ethernet Auto-Discovery, but I don't think that's what we're looking for in this case. I might lean towards Type 2, but I need to double-check my notes.

I feel like Type 4 is related to multicast, but I'm not confident about how it applies here. I should have reviewed that section more thoroughly.

This question seems similar to one we practiced where we discussed how broadcast traffic is handled in multihomed setups. I think Type 3 might be the right answer based on that.

I remember studying EVPN route types, but I'm not entirely sure which one corresponds to this scenario. I think it might be Type 2, but I could be wrong.

I've got a good feeling about this one. The mention of unicast and broadcast traffic patterns points me towards Type 3 EVPN routes. I'm going to go with that as my answer.

I'm a bit confused by the wording of the question. It's not entirely clear to me how the different EVPN route types would impact the traffic behavior described. I'll need to think this through carefully.

Okay, the key details here are that CE-2 receives unicast traffic from both links, but broadcast traffic on only one link. That sounds like it could be a Type 3 EVPN route, which is used for multi-homing.

Hmm, the question mentions unicast and broadcast traffic, so I'm thinking the answer might be related to how EVPN handles those different traffic types. I'll need to refresh my knowledge on that.

This looks like a tricky EVPN question. I'll need to carefully review the details about the different EVPN route types to determine which one enables the behavior described.

I'm pretty confident I can solve this one. The key is understanding how abstract classes and interfaces work in Java. I'll carefully go through each class definition and select the right answer.

Wait, is this a real exam question or did someone just make it up to mess with us? Either way, I'm going with Type 3. It's the only one that makes sense, unless CE-2 is just having a bad day.

Ah, the old EVPN route type conundrum. I bet the answer is Type 3, but I always get these mixed up. Maybe I should have paid more attention in class...

Definitely Type 3! The question is so clear about the multihomed links and broadcast traffic. Type 3 is the way to go here.

Hmm, I'm not sure about this one. Maybe Type 2? That's used for MAC/IP advertisement, and the question talks about unicast traffic from CE-1 to CE-2.

I think the answer is Type 3. The question mentions broadcast traffic, and Type 3 routes are used for Ethernet Segment information, which includes multihoming details.

Interesting point, Nakisha. I see your rationale. Let's wait and see what others think.
NA
Nakisha

I disagree, I believe the correct answer is Type 4 as it is specifically designed for this behavior.

I think the answer is Type 3 because it allows for broadcast traffic to be received on only one link.
