Which feature permits granular control of per-VNI type-2 and EVPN type-3 routes across an entire overlay network?
Which feature permits granular control of per-VNI type-2 and EVPN type-3 routes across an entire overlay network?
Route targets permit granular control of per-VNI type-2 and EVPN type-3 routes across an entire overlay network. They define how routes are imported and exported between different virtual routing and forwarding instances (VRFs), thus effectively managing the distribution of routes within the overlay network.
You are designing an IP fabric underlay network in your data center. You must ensure that your traffic can be forwarded at line rate.
In this scenario, which oversubscription model should be used?
To ensure that traffic can be forwarded at line rate in an IP fabric underlay network, the oversubscription model used should be 1:1. This means that the available bandwidth will match the required bandwidth, ensuring no congestion and optimal performance. This model ensures that there is no oversubscription, which aligns with the requirement to forward traffic at line rate.
Which two statements about a DHCP relay in an EVPN-VXLAN fabric are correct? (Choose two.)
In an EVPN-VXLAN fabric, DHCP relay allows the DHCP client and DHCP server to reside in different routing instances. This feature is essential for enabling DHCP relay functionality across routed infrastructures where clients and servers are not within the same VLAN or subnet. Additionally, both virtual gateway and anycast gateway addressing are supported in EVPN-VXLAN fabrics. These technologies enhance the fabric's scalability and redundancy by allowing multiple devices to share the same IP address for gateway functionalities.
Which two statements about the seamless EVPN-VXLAN stitching data center interconnect architecture are correct? (Choose two.)
VXLAN stitching is supported in both 3-stage and 5-stage fabrics, making it a versatile solution for different data center architectures. Additionally, VXLAN stitching is particularly beneficial and ideal for medium to large data center designs. It helps in managing scalability and maintaining efficient communication without the need for a full mesh of VXLAN tunnels, which can be complex and less efficient.
Which IP fabric underlay protocol provides the highest degree of scalability?
Border Gateway Protocol (BGP) provides the highest degree of scalability among the given options. It is widely used in large-scale networks, such as internet backbones, because of its ability to handle a vast number of routes and its support for policy-based routing. BGP is designed to manage many connections and routes efficiently, making it the preferred choice for scalable IP fabric underlay protocols.
