In a scenario where a VXLAN tunnel is dynamically established through BGP EVPN, which of the following statements about symmetric IRB forwarding are correct?
A.
Both the ingress VTEP and egress VTEP forward packets based on the Layer 3 forwarding table.
B.
The ingress VTEP forwards packets based only on the Layer 2 forwarding table.
C.
The egress VTEP forwards packets based only on the Layer 2 forwarding table.
D.
When VTEPs forward inter-subnet user communication packets, the VNI carried in the VXLAN header is the L3VNI.
VXLAN supports inter-subnet routing using Integrated Routing and Bridging (IRB). In symmetric IRB, both ingress and egress VTEPs perform Layer 3 forwarding to ensure efficient packet forwarding across subnets.
✅ A. Both the ingress VTEP and egress VTEP forward packets based on the Layer 3 forwarding table.
In symmetric IRB, both ingress and egress VTEPs perform Layer 3 lookup and forwarding.
The ingress routes packets before encapsulating them in VXLAN, and the egress performs another Layer 3 lookup to determine final delivery.
✅ D. When VTEPs forward inter-subnet user communication packets, the VNI carried in the VXLAN header is the L3VNI.
L3VNI (Layer 3 VXLAN Network Identifier) is used for inter-subnet routing between VXLAN segments.
