Re: Failover IPv6 with multiple PA prefixes (Was: IPv6 fc00::/7 — Unique local addresses)

Now the problem with such a setup is the many locations where you actually are hardcoding the IP addresses/prefixes into: firewalls, DNS etc. That is the hard part to solve, especially when these services are managed by other parties.

And probably the reason why most won't deploy RA and multiple prefixes. Hardcode and NAT, baby!
