IOS-XR: Stuck between SNMP and SDN

SNMP may be outdated, and is definitely unloved, but it still serves a purpose. We’re moving to a new world, with new methods and data structures for interrogating and configuring our network devices. This is a Good Thing, but we’re not there yet, and this leaves us stuck in limbo for trying to solve Real World problems today. Here’s what I found recently when trying to do some network monitoring with IOS-XR devices.
