EVPN-VXLAN Signaling

Click the Exhibit button.

Question Image

You have deployed an EVPN-VXLAN data center. Device server1 must be able to communicate with device server2.

Referring to the exhibit, which two statements are correct?

Choose two
  • A Traffic from server1 to server2 will transit a VXLAN tunnel to spine1 or spine2, then a VXLAN tunnel from spine1 or spine2 to leaf2.
  • B Traffic from server1 to server2 will transit the VXLAN tunnel between leaf1 and leaf2.
  • C An IRB interface must be configured on leaf1 and leaf2.
  • D An IRB interface must be configured on spine1 and spine2.
Explanation

Because the endpoints use different IP subnets, their traffic must be routed. This design uses leaf switches as L2 gateways/VTEPs and spine switches as L3 gateways, so traffic is VXLAN-encapsulated from leaf1 to a spine, routed there, and VXLAN-encapsulated from the spine to leaf2. The L3 gateway function requires IRB interfaces on spine1 and spine2.
