Configuring Advertisement Prefixes
To configure the RADVD available prefixes:
STEP 1 Choose Networking > IPv6 > Advertisement Prefixes.
STEP 2 Click Add Row.
STEP 3 Enter this information:
Router Preference 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.
MTU MTU size (0 or 1280 to 1500). The default is 1500
bytes.
The Maximum Transmit Unit (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.
Router Life Time Router lifetime value or the time in seconds that the
advertisement messages exists on the route. The
default is 3600 seconds.
