After booting, a client receives an ICMPv6 RA message with the M flag set to 0 and the O flag set to 1. What does this indicate?

• The client should request an IPv6 address directly from a DHCPv6 server.
• The client should automatically configure an IPv6 address and then contact a DHCPv6 server for more information.
• The client should automatically configure an IPv6 address without contacting a DHCPv6 server.
• The client should be statically configured with an IPv6 address because the local router does not support autoconfiguration.

Explanation: The Managed Address Configuration (M) flag and the Other Configuration (O) flag in ICMPv6 RA messages are used to indicate to an IPv6 client how it should configure its IPv6 addresses. If the M flag is set to 0 it means that the host should automatically configure its own IPv6 interface address rather than asking for one from a DHCPv6 server. If the O flag is set to 1, it means that the client can find additional addressing information, such as a DNS server address, by contacting a DHCPv6 server after it has automatically configured its own address.
