IPv6 suppress or not to suppress

[Rolando Valenzuela]

I understand the benefits of auto-configuration and the purposes of RA messages and so on, but I was wondering if from a controlled environment where all the IPs will be configured manually, if it is recommended to suppress all the RA messages.

Let say a production network with dual stack, if I don't want the rest of servers on that IPv4 network to dynamically get an IPv6 address, something like this may work? it is recommended?

interface GigabitEthernet 0/12
  ipv6 address 2001:db8:1234:5678::1/64
  ipv6 nd prefix no-autoconfig
  ipv6 nd suppress-ra
  ipv6 nd ra suppress all

So the only way for a server to join this IPv6 network is with manual configuration.

Any suggestions will be highly appreciated.

Thanks!

I think you are doing the right thing.

Suppressing the advertisement of RAs from the Router should avoid hosts on the LAN to unexpectedly join the IPv6 network.
