Question 36/85
What are two requirements for an IP fabric? (Choose two.)
Correct Answer: A,B
AnIP fabricis a network architecture commonly used in data centers to provide scalable, high-throughput connectivity using aspine-leaf topology.
Step-by-Step Breakdown:
* Layer 3 Routing Protocol:An IP fabric relies on aLayer 3 routing protocol, typically BGP or OSPF, to provide routing between the leaf and spine switches. This ensures efficient traffic forwarding across the network.
* Single Connection Between Spine and Leaf:In an IP fabric, each leaf switch connects toevery spine switchwith a single connection. This ensures that traffic between any two leaf switches can travel through the spine layer in just two hops.
Juniper Reference:
* Spine-Leaf Design: Juniper's IP fabric implementations are designed for scalability and low-latency routing, often using protocols like BGP for Layer 3 control.
