Refer to the exhibit. A network administrator is implementing stateful DHCPv6 operation for the company. However, the clients are not using the prefix and prefix-length information that is configured in the DHCP pool. The administrator issues a show ipv6 interface command. What could be the cause of the problem?
- No virtual link-local address is configured
- The Duplicate Address Detection feature is disabled
- The router is configured for SLAAC DHCPv6 operation
The router is configured for stateless DHCPv6 operation*
The router is configured for stateless DHCPv6 operation, which is shown by the last two lines of the show command output. Hosts will configure their IPv6 addresses by using the prefix information that is provided by RA messages. They will also obtain additional configuration information from a DHCPv6 server. The “No virtual link-local address” option and the “Duplicate Address Detection” option are irrelevant to DHCP configuration. Option “SLAAC configuration” is incorrect because by definition SLAAC will use only the information that is provided by RA messages to configure IPv6 settings.
