The video demonstrate an alternative to IPv6 address assignment with Stateful Autoconfiguration on Cisco router. The concept of DHCP in IPv6 has changed slightly where DHCP server no longer provides subnet mask and default gateway, but instead end-hosts obtain these information through Router Advertisement. We will look at how we can use Other and Managed Config flags to control what type of information end-hosts would obtain from a DHCP server. A router and Windows 7 computer will be used as our test clients in this lab.
