The Ingress VTEP performs both Layer 2 and Layer 3 table lookup for packet forwarding. The forwarding mode is _____ IRB forwarding. (Capitalize the first letter.)
IntegratedIn VXLAN networking, IRB (Integrated Routing and Bridging) forwarding is used to support routing between VXLAN segments (BDs or VLANs).There are two types of IRB modes:Integrated IRB Forwarding:The ingress VTEP performs both Layer 2 and Layer 3 lookups.This allows routing to be handled within the same VTEP.Ensures efficient and low-latency forwarding.This is the default and recommended mode in most Huawei CloudCampus and data center VXLAN deployments.Distributed IRB Forwarding:The ingress VTEP performs only L2 lookup, and routing is handled at the egress VTEP.Given the question says the Ingress VTEP performs both Layer 2 and Layer 3 lookup, the correct IRB mode is:Integrated IRB ForwardingCorrect answer: Integrated
