I am looking to turn off the SLAAC addressing for a vlan interface that Windows servers and network devices will use. We will manually set the IPv6 addresses and do not want the SLAAC addressing.
I put these on the vlan interface -- similar to what we did for DHCPv6 addressing - for this purpose, I just put the address as all 0's.
ipv6 nd prefix 0000:000:0000:000::/64 no-advertise
ipv6 nd managed-config-flag
ipv6 nd ra suppress
I left out the link-local and the IPv6 address commands, but they are there.
