prefix1/prefix2
Enabled Click this to enable or disable the following prefix-specific flags.
prefix
Enter the network prefix or the address of the interface.
AdvOnLinkFlag Indicates that this prefix can be used for on-link determination.
Click to set this to on.
AdvAutonomousFlag Indicates that this prefix can be used for autonomous address
configuration. Click to set this to on.
AdvValidLifetime
The length of time (in seconds) that the prefix will be valid for
the purpose of on-link determination. Enter either an integer or
the word infinity.
AdvPreferredLifetime The length of time (in seconds) that addresses generated
from the prefix via stateless address autoconfiguration remain
preferred. Enter either an integer or the word infinity.
AdvRouterAddr
When set, indicates that the address of the interface will be sent
instead of the network prefix. Click this to set it to on.
If6to4
If an IPv4 address is entered, the prefix will be combined with the
IPv4 address to produce a valid 6to4 prefix. This option allows
systems with dynamic IPv4 addresses to update their advertised
6to4 prefixes by restarting RADVD or by sending a signal to
cause RADVD to reconfigure itself.
