Answer:

Explanation:
VNIInstatic
Explanation:
VXLAN tunnel configuration, you donot use a control planelike BGP EVPN. Instead, youmanually configureall necessary forwarding parameters, including:VNI (VXLAN Network Identifier): Identifies the VXLAN segment.VTEP IP Address: The remote tunnel endpoint.Ingress Replication List: Required for multicast emulation (flooding/BUM traffic) in the absence of a multicast control plane.Whenconfiguring statically, theVNIis essential to map Layer 2/3 services to the correct VXLAN segment.Thus, the correct word to complete the sentence is:VNICorrect answer: VNI


NEW QUESTION # 233
Which of the following statements about BGP EVPN principles are correct in a scenario where a VXLAN tunnel is dynamically established through BGP EVPN?

Answer: A,B,C

Explanation:
BGP EVPN in VXLAN Tunneling
#A. MP_REACH_NLRI is used to carry routing information.
MP_REACH_NLRI (Multiprotocol Reachable Network Layer Reachability Information)is used inBGP updatesto carryVXLAN reachability information.
#B. Several BGP EVPN routes are defined through BGP extension.
BGP EVPN introduces multiple route types, such asType 2 (MAC/IP Advertisement), Type 3 (Inclusive Multicast), and Type 5 (IP Prefix Advertisement).
#D. MP_REACH_NLRI is used to carry the RT.
RT (Route Target) defines route import/export policies in VPN environments.
MP_REACH_NLRI carries the RT attributein BGP EVPN updates.
