Trying out IPv6 in the data centre without redundancy at first

Summary

Manuel Schmitt describes an early IPv6 connection in alpha stage with one router, one carrier and BGP, but no redundancy yet. The test connection ran over exactly one router. Only one carrier was involved.

Ideas

  • An alpha network may deliberately not carry the same availability promises as production.
  • BGP alone creates no redundancy if there is only one router and one carrier.
  • A clearly limited internal test prevents premature expectations among customers.

Insights

  • Naming the level of maturity is part of a responsible infrastructure rollout.
  • New protocols first need observability and operational routine before external testers are added.

Facts

  • Routing already used BGP, although no customer test was planned yet.

Recommendations

  • Document missing redundancy and concrete abort criteria for an alpha operation.
  • Add a second router, a second uplink and independent monitoring before customers use it.

IPv6: getting over the first hurdles

Jens Link introduces IPv6 and explains addresses, prefixes, automatic configuration and the practical differences from familiar IPv4 operations. IPv6 works more easily as a new operating model than as an enlarged IPv4. Experimenting early prevents a hectic migration later under address pressure.
