HP Exam HPE7-A04 Topic 2 Question 17 Discussion

Actual exam question for HP's HPE7-A04 exam

Question #: 17
Topic #: 2

You are adding EVPN VXLAN to an L3 spine and leaf topology that uses OSPF for the underlay. You plan to use a single BGP AS. Which design for EVPN neighbors is correct?

ALeaf switches should establish iBGP sessions with other leaf switches using their VXLAN loopback IPs. Route reflectors are not required

BThe border leaf switches should act as route reflectors and specify the leaf switches' VXLAN loopback IPs as route reflector clients

CAt least one spine switch should act as route reflector and specify the leaf switches' unique loopback IPs as route reflector clients

DLeaf switches should establish iBGP sessions with spine switches on their actual P2P link IP addresses. Route reflectors are not required

I'm just picturing the poor sysadmin trying to keep track of all those VXLAN loopback IPs. Option C is the way to go, for sure.

Haha, option D? What is this, amateur hour? Route reflectors are a must-have in this scenario.

I don't know, I'd probably go with option B. The border leaf switches can handle the route reflector duties, right?

Option B is correct. The border leaf switches can act as route reflectors for the leaf switches.

Option C seems like the way to go. Having a spine switch as the route reflector just makes sense in this topology.

Using the leaf switches' unique loopback IPs as route reflector clients also ensures a more efficient routing process.

It definitely helps with scalability and reduces the complexity of the configuration.

I agree, having a spine switch as the route reflector simplifies the design.
