STEP 1 Click IP Configuration > IPv6 Management and Interfaces > IPv6 Router
Configuration > Router Advertisement.
STEP 2 To configure an interface listed in the Router Advertisement Table, select it and
click Edit.
STEP 3 Enter the following fields:
• Suppress Router Advertisement—Select Ye s to suppress IPv6 router
advertisement transmissions on the interface. If this feature is not
suppressed, enter the following fields.
• Router Preference—Select either Low, Medium or High preference for the
router. Router advertisement messages are sent with the preference
configured in this field. If no preference is configured, they are sent with a
medium preference.
Associating a preference with a router is useful when, for example, two routers
on a link provide equivalent, but not equal-cost, routing, and policy may dictate
that hosts should prefer one of the routers.
• Include Advertisement Interval Option—Select to indicate that an
advertisement option will be used by the system. This option indicates to a
visiting mobile node the interval at which that node may expect to receive
router advertisements. The node may use this information in its movement
detection algorithm.
• Hop Limit—This is the value that the router advertises. If it is not zero, it is
used as the hop limit by the host.
• Managed Address Configuration Flag—Select this flag to indicate to
attached hosts that they should use stateful auto configuration to obtain
addresses. Hosts may use stateful and stateless address auto configuration
simultaneously.
• Other Stateful Configuration Flag—Select this flag to indicate to attached
hosts that they should use stateful auto configuration to obtain other (non
address) information.
NOTE If the Managed Address Configuration flag is set, an attached host can
use stateful auto configuration to obtain the other (non address) information
regardless of the setting of this flag.
• Neighbor Solicitation Retransmissions Interval—Set the interval to
determine the time between retransmissions of neighbor solicitation
messages to a neighbor when resolving the address or when probing the
reachability of a neighbor.
