We have completed deployment of our local (non-authoritative) Internet Route Registry (IRR) mirror, which has already yielded some impressive benefits for members.
Route server configuration generation and update times have been cut from approximately 15 minutes to approximately one minute. These times apply to the removal of prefix-set expansion from configuration updates as we currently do not filter on prefix-sets. But even with prefix-set generation included, the generation and update times are now only about 5 minutes – this is one-third of what they used to be!
Additionally, generation/update runs are no longer failing due to connectivity issues or rate limiting by upstream IRR database providers. This was a consistent issue we were running into, especially when an out-of-cycle update was requested by a member to incorporate a change to their allowed ASNs or prefixes.
