Re: IPv6 RA vs DHCPv6 - The chosen one?

In many environments RA is a catastrophic disaster. Some operators need to be able to do everything with RA turned off on routers, disabled on hosts and filtered on switches.

While in some environments, typically with small number of devices, its indispensable. Small businesses may not want the complexity of setting up a central server (for DHCP) - SLAAC works very well in such environments. Today, we can get NTP server information only with DHCP (DNS info is supported by both DHCP and RAs). DHCP only works after RAs have been processed. In some environments (mobile IPv6) delays in acquiring NTP and other servers information is critical and waiting for DHCP to come up may not be acceptable. Glen
