Cisco RV180/RV180W Administration Guide
Under Advertise Mode, choose one of the following:
• Unsolicited Multicast—Select this option to send router advertisements
(RAs) to all interfaces belonging to the multicast group.
• Unicast only—Select this option to restrict advertisements to well-known
IPv6 addresses only (router advertisements [RAs] are sent to the interface
belonging to the known address only).
If you chose Unsolicited Multicast in Step 3, enter the advertise interval. The
advertise interval is a random value between the Minimum Router Advertisement
Interval and Maximum Router Advertisement Interval. (MinRtrAdvInterval = 0.33 *
MaxRtrAdvInterval.) The default is 30 seconds.
Under RA Flags, check Managed to use the administered/stateful protocol for
address auto configuration. Check Other to use the administered/stateful protocol
of other, non-address information auto configuration.
Under router preference, choose Low, Medium, or High. The router preference
provides a preference metric for default routers. The low, medium and high values
are signaled in unused bits in Router Advertisement messages. This extension is
backward compatible, both for routers (setting the router preference value) and
hosts (interpreting the router preference value). These values are ignored by hosts
that do not implement router preference. This feature is useful if there are other
RADVD-enabled devices on the LAN. The default is high.
Enter the MTU size. The MTU is the size of the largest packet that can be sent over
the network. The MTU is used in RAs to ensure all nodes on the network use the
same MTU value when the LAN MTU is not well-known. The default is 1500 bytes.
Enter the router lifetime value, or the time in seconds that the advertisement
messages will exist on the route. The default is 3600 seconds.
Click Save.
