A. B. C. D. E. F.CEF.
E VPN (Ethernet VPN) is a type of network virtualization technology used in data center networks. It provides Layer 2 and Layer 3 connectivity between different sites in a scalable and efficient manner. In E VPN, vPC (virtual PortChannel) is a technology used to create a loop-free, redundant topology between two switches.
In this question, we are asked about the configurations that can be different between E VPN vPC peers. Let's go through each answer option to understand which ones are correct.
A. Using the same primary IP addresses: This configuration should be the same between E VPN vPC peers. Primary IP addresses are used to identify the switch and must be unique within the network. If two switches have the same primary IP address, it will cause a conflict and disrupt the network.
B. Loopback primary IP address: The loopback primary IP address is used for internal communication between the switches. This configuration can be different between E VPN vPC peers as long as they are unique within the network.
C. Consistent NVE1 binding to the same loopback interface: NVE (Network Virtualization Edge) is the interface that connects the switch to the overlay network. This configuration should be the same between E VPN vPC peers. If the NVE1 binding is different, it can cause issues with communication between the switches.
D. Using a different secondary IP address: Secondary IP addresses are used for additional Layer 3 connectivity. This configuration can be different between E VPN vPC peers as long as they are unique within the network.
E. Consistent VNI to group mapping: VNI (Virtual Network Identifier) is used to identify the virtual network. This configuration should be the same between E VPN vPC peers. If the VNI to group mapping is different, it can cause issues with communication between the switches.
F. Consistent VLAN to VN-segment mapping: VLAN to VN-segment mapping is used to map the VLAN to the corresponding virtual network. This configuration should be the same between E VPN vPC peers. If the mapping is different, it can cause issues with communication between the switches.
Based on the above explanations, the correct answers to this question are: B, D, and E. The loopback primary IP address, the secondary IP address, and the VNI to group mapping can be different between E VPN vPC peers.
