Description

The Domino router caches the calculated routing paths between domains so it does not have to resolve the topology again for every mail. RouterPathCheckInterval controls how often this cache is reconciled with the directory and connection documents. Short intervals (e.g. 5 minutes) make topology changes take effect quickly, but cost a little CPU. Longer intervals (30–60 minutes) are resource-friendly, but can mean that mails are still sent over the old route briefly after a topology change.

Example configuration

RouterPathCheckInterval=10

Notes & pitfalls

  • Choose the value in line with the update frequency of the directory.
  • Takes effect after a router restart.
  • Manual recomputation is possible at any time via tell router update config.
  • For cluster setups with frequent failovers, prefer short intervals.
