Refer to the Cisco IOS DHCPv6 configuration shown in the exhibit.
Which statement is correct?
A.
The configuration is missing a command under interface Gi0/1 to indicate to the attached hosts
to use stateful DHCPv6 to obtain their IPv6 addresses
B.
The IPv6 router advertisements indicate to the attached hosts on the Gi0/1 interface to get
other information besides their IPv6 address via stateless auto configuration
C.
The IPv6 DHCPv6 server pool configuration is misconfigured
D.
The DNS server address can also be imported from another upstream DHCPv6 server
Interface is missing: ipv6 nd managed-config-flag
Command instructs a client to start a DHCP solicit phase to find a DHCP server. The command sets the “managed address configuration highlight” in IPv6 router advertisements indicating to attached hosts they should use DHCPv6 to obtain addresses.
From Cisco book :
If the “managed address configuration” flag is set using the ipv6 nd managed-config-flag command, then an attached host can use stateful autoconfiguration to obtain the other (nonaddress) information regardless of the setting of the “other stateful configuration” flag.
So I guess A is not right …. But B also mention “via stateless auto configuration” and not via stateful
So now I’m confused
jslaven is correct. The “ipv6 nd managed-config-flag” indicates clients to use DHCPv6 to obtain addresses. The existing “ipv6 nd other-config-flag”, tells clients to grab other parameters from DHCPv6 such as DNS, TFTP, etc.
