Select the advertisement mode from the drop-down list.
• Unsolicited Multicast – Sends Router Advertisement messages to all interfaces in
the multicast group. Enter the Advertisement Interval. This option is the default
setting.
• Unicast – Send Router Advertisement messages only to well-known IPv6 addresses.
Enter the time interval between 10 and 1800 (Default is 30 seconds) at which the router
advertisement messages are sent.
Determines whether hosts can use DHCPv6 to obtain IP addresses and related information.
Check one of the following:
• Managed – Hosts use an administered, stateful configuration protocol (DHCPv6)
to obtain stateful addresses and other information through DHCPv6.
• Other – Uses an administered, stateful configuration protocol (DHCPv6) to obtain
other, non-address information, such as DNS server address.
Preference metric used in a network topology where multi-homed hosts have access to
multiple routers. Router Preference helps a host to choose an appropriate router. There
are three preferences to choose from, such as High, Medium, or Low. The default setting
is High. Select the preference from the drop-down list.
Maximum Transmission Unit (MTU) is the size of the largest packet that can be sent
over the network. MTUs are used in Router Advertisement messages to ensure that all
nodes on the network use the same MTU value when the LAN MTU is unknown. The
default setting is 1500 bytes, which is the standard value for Ethernet networks. For
PPPoE connections, the standard is 1492 bytes. Unless your ISP requires a different
setting, this setting should not be changed. Enter a value between 1280 and 1500.
Time in seconds that the Router Advertisement messages exist on the route. Enter time
in seconds. The default is 3600 seconds.
