Configuring Advertisement Prefixes

To configure the RADVD available prefixes:
Choose Networking > IPv6 > Advertisement Prefixes.
Click Add Row.
Choose low, medium, or high from the drop-down
menu. The default is medium.
The router preference provides a preference
metric for default routers. The low, medium and
high values are signaled in unused bits in RA
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.
Enter the MTU size (0 or 1280 to 1500). The default
is 1500 bytes.
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.
Enter the router lifetime value, or the time in
seconds that the advertisement messages exists
on the route. The default is 3600 seconds.
