Exhibit.
You are troubleshooting an IP fabric (or your data center. You notice that your traffic is not being load balanced to your spine devices from your leaf devices. Referring to the configuration shown in the exhibit, what must be configured to solve this issue?
Understanding ERB Architecture:
ERB (Edge Routed Bridging) architecture is a network design where the routing occurs at the edge (leaf devices) rather than in the spine devices. In a VXLAN overlay network with EVPN as the control plane, leaf devices typically act as both Layer 2 (L2) and Layer 3 (L3) VXLAN gateways.
Placement of VXLAN Gateways:
Option B: All leaf devices will have L2 VXLAN gateways to handle the bridging of VLAN traffic into VXLAN tunnels.
Option C: All leaf devices will also have L3 VXLAN gateways to route traffic between different VXLAN segments (VNIs) and external networks.
Option E: Spine devices in an ERB architecture generally do not function as VXLAN gateways. They primarily focus on forwarding traffic between leaf nodes and do not handle VXLAN encapsulation/decapsulation.
Conclusion:
Option B: Correct---All leaf devices will have L2 VXLAN gateways.
Option C: Correct---All leaf devices will have L3 VXLAN gateways.
Option E: Correct---Spine devices will not act as VXLAN gateways
