IPv6 Router Configuration
The following sections describe how to configure IPv6 routers. It covers the following topics:
• Router Advertisement
• IPv6 Prefixes
Router Advertisement
IPv6 routers are able to advertise their prefixes to neighboring devices. This feature can be
enabled or suppressed per interface, as follows:
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.
