A large IP fabric uses iBGP as the underlay. The network team wants to scale the fabric to support 500 leaf switches. They are considering two options: (1) using route reflectors on the spine switches, or (2) using BGP confederations. Which factor should drive their decision?

Confederations eliminate the need for a full mesh of iBGP sessions within each sub-AS.

Route reflectors reduce the number of iBGP sessions more effectively than confederations in a spine-and-leaf topology.

Route reflectors are only supported on spine switches.

Confederations are required when using eBGP as the underlay.

What is a common operational challenge when scaling an IP fabric?

Managing the increased complexity of configuration and troubleshooting

Eliminating the need for routing protocols

Reducing the number of available IP addresses

Decreasing the number of VLANs that can be supported
