After VTEP devices have established BGP neighbor adjacencies with other VTEPs or with Internal BGP route reflectors, which three pieces of information are exchanged through BGP? (Choose three.)
When VTEP devices establish BGP neighbor adjacencies with other VTEPs or Internal BGP route reflectors in a VXLAN (Virtual Extensible LAN) environment, the following three pieces of information are exchanged through BGP:
A. VTEP address: The VTEP address is exchanged through BGP to identify each VTEP device in the VXLAN network. This information is crucial for proper communication between VTEPs.
B. VTEP peer list: BGP exchanges the list of VTEP peers to which a particular VTEP is connected. This information is used to maintain a complete view of the VXLAN network topology.
C. VPNv4 prefixes: BGP exchanges VPNv4 prefixes, which are the customer routes that are being advertised by the VXLAN network. These prefixes are used to populate the VTEP's local VNI (Virtual Network Identifier) routing table.
D. Router MAC address: The router MAC address is not exchanged through BGP in a VXLAN environment. The MAC address is used to identify the source and destination of the VXLAN encapsulated packets.
E. Layer 3 VNI: The Layer 3 VNI is not exchanged through BGP. The VNI is used to identify the particular VXLAN overlay network on which the packet is being transmitted.
In summary, BGP exchanges the VTEP address, VTEP peer list, and VPNv4 prefixes in a VXLAN environment to establish and maintain the proper communication between VTEPs and to populate the VTEP's local VNI routing table with the customer routes being advertised.
