Description
Community Fibre are a growing FTTH provider in London. We have 150kms of
fibre in the ground chiefly via PIA, we have passed over 75,000 homes
and plan to pass 500,000 homes by the end of 2021.
Provisioning of IPv4 public addresses was not scaling well as the
network grew and additionally our original distributed DHCP deployment
didn't support IPv6 prefix delegation, preventing us from introducing
IPv6 to our customers the way we wanted to. We revisited our design and
decided to update to a more centralized model, selecting ISC's Kea DHCP
from a number of other vendor servers for a rollout of IPv6 to existing
clients.
This talk is about the transition from where we were to where we are now
- having introduced IPv6 to our customer base and now seeing 25%
of our total customer traffic running over IPv6. There were some
hiccups along the way, so we're going to run through the details of
those teething problems, how they were overcome and what we learned from
them and then end with our future plans which include migration of IPv4
to join IPv6 on the new Kea servers and improvements to the management,
reporting and resilience of our redesigned solution.
