The following configuration is applied to a router at a branch site:
ipv6 dhcp pool dhcp-pool dns-server 2001:DB8:1:B::1 dns-server 2001:DB8:3:307C::42 domain-name example.com !
If IPv6 is configured with default settings on all interfaces on the router, which dynamic IPv6 addressing mechanisms could you use on end hosts to provide end-to-end connectivity?
