How to disable SLAAC ipv6 auto configuration on Juniper

In this video I demonstrate using my Juniper vEX switch how to disable clients from DHCPv6 clients from using SLAAC auto confiuration to automatically an IPv6 address from a configured router advertisement. The SLAAC process is a stateless method in IPv6 for client to obtain an IPv6 address on their own using the EUI-64 process as well as generate temporary IPv6 addresses. Below is link to Juniper's official documentation for how to configure a DHCPv6 server on Junos: https://supportportal.juniper.net/s/article/How-to-provide-IPv6-stateful-autoconfiguration-via-DHCPv6?language=en_US
