Which two statements describe an IP fabric? (Choose two.)

An IP fabric is a modern network architecture, typically built using a spine-and-leaf (or Clos) topology. This design uses Layer 3 routing protocols, such as BGP, throughout the network. Key characteristics include the use of spine and leaf devices for a scalable, non-blocking, and predictable structure. This architecture inherently supports traffic load sharing across multiple active paths using Equal-Cost Multi-Path (ECMP) routing, which enhances performance and resiliency by distributing traffic across all available spine links.

A. In a spine-leaf fabric, any leaf is two hops away from any other leaf (leaf-spine-leaf), not one hop.

B. A primary design goal of an IP fabric is to minimize or eliminate large Layer 2 domains and reliance on protocols like STP, favoring Layer 3 routing instead.

"Data Center Fabric Architectures Guide"

section "IP Fabric Architecture". It states

"An IP fabric is a data center network topology built using spine and leaf devices... The IP fabric uses a Layer 3 BGP-based routing protocol to exchange reachability information."

2. Juniper Networks Documentation

"EVPN-VXLAN Campus Architecture Guide"

section "IP Fabric Underlay". It describes the underlay as a "spine-and-leaf IP fabric" and mentions

"The IP fabric uses ECMP to load-balance traffic across multiple links".
