In the exhibit, the EVPN-IRB is using the interface-ful unnumbered model and is fully operational. Which of the following statements is FALSE?
B) An MP-BGP session that supports the advertisement of EVPN routes is established between PEI and PE2.
A) An MP-BGP session that supports the advertisement of VPN-IPv4 routes is established between PE3 and PE4.
C) On PE3, the routing table for VPRN 15 contains an entry for 10.10.1.0/24. This entry is resolved to MAC-OI as an overlay index.
D) On PE3, the routing table for VPRN 15 contains an entry for 10.10.4.0/24. This entry is resolved using a transport tunnel towards PE

I'm leaning towards option B being false, but I need to double-check what I learned about EVPN route advertisements between PEs.

I practiced a similar question where we had to identify false statements about EVPN configurations, and I feel like it could be option D since it mentions a transport tunnel.

I think option C sounds familiar, but I can't recall if MAC-OI is specifically mentioned in the context of VPRN entries.

I remember studying the differences between MP-BGP sessions for EVPN and VPRN, but I'm not entirely sure which statement is false here.

This question requires a good understanding of EVPN concepts. I'll need to carefully read through the options and think about how the EVPN-IRB is supposed to function in this case.

Alright, this seems straightforward enough. I just need to understand the interface-ful unnumbered model and how it relates to the EVPN-IRB functionality. Then I can confidently select the false statement.

Okay, let's see here. The question is asking which statement is false, so I'll need to analyze each option closely to identify the one that doesn't match the given information.

I'm a bit unsure about the details of EVPN and how the routing table entries should be resolved in this scenario. I'll need to review my notes and try to connect the dots.

I wonder if the EVPN-IRB is using the interface-ful unibrow model instead. That would be a whole different kind of operational challenge!

Option D is correct. The routing table for VPRN 15 on PE3 contains an entry for 10.10.4.0/24 that is resolved using a transport tunnel towards PE4.

Option A is correct. The EVPN-IRB is using the interface-ful unnumbered model, so there must be an MP-BGP session established between the PEs to advertise VPN-IPv4 routes.

I'm not sure, but I think option A could also be false because the MP-BGP session should support the advertisement of VPN-IPv4 routes, not just VPN-IPv4 routes.
