• RA Flags: Choose whether or not hosts can use DHCPv6 to obtain
addresses and other information. The options are described below.
- Enabling the Managed flag only: Check the Managed box if you want
hosts to use an administered /stateful configuration protocol (DHCPv6)
to obtain stateful addresses and other information through DHCPv6.
- Enabling the Other flag only: Check the Other box if you want hosts to
use an administered/stateful configuration protocol (DHCPv6) to obtain
other, non-address information, such as DNS server addresses.
- Enabling both flags: Check both boxes if you want hosts to obtain
addresses and other information through DHCPv6.
- Disabling both flags: Uncheck both boxes if you want hosts to obtain
addresses and other information through router advertisements and not
DHCPv6.
• Router Preference: Choose High, Medium, or Low. This preference metric
is useful in a network topology in which multi-homed hosts have access to
multiple routers. This metric helps a host to choose an appropriate router. If
two routers are reachable, the one with the higher preference will be
chosen. These values are ignored by hosts that do not implement router
preference. The default setting is High.
• MTU: Enter the size of the largest packet that can be sent over the network.
The MTU (Maximum Transmission Unit) is used in Router Advertisement
messages to ensure that all nodes on the network use the same MTU value
when the LAN MTU is not well-known. The default setting is 1500 bytes,
which is the standard value for Ethernet networks. For PPPoE connections,
the standard is 1492 bytes. Unless your ISP requires a different setting, this
setting should not be changed.
• Router Lifetime: Enter the time in seconds that the Router Advertisement
messages will exist on the route. The default is 3600 seconds.
