21 # These settings cause advertisements to be sent every 3-10 seconds. This
22 # range is good for 6to4 with a dynamic IPv4 address, but can be greatly
23 # increased when not using 6to4 prefixes.

31 # the router for the purposes of default router determination.

54 # Note that the first 48 bits are specified here as zeros. These will be
55 # replaced with the appropriate 6to4 address when radvd starts or is
56 # reconfigured. Be sure that the SLA ID (1234 in this case) is specified
59 prefix 0:0:0:1234::/64
66 # This setting causes radvd to replace the first 48 bits of the prefix
67 # with the 6to4 address generated from the specified interface. For example,
68 # if the address of ppp0 is 192.0.2.25 when radvd configures itself, this
69 # prefix will be advertised as 2002:C000:0219:1234::/64.
71 # If ppp0 is not available at configuration time, this prefix will not be
72 # advertised, but other prefixes listed in the configuration will be
73 # advertised as usual.
75 # When using the Base6to4Interface option, make sure radvd receives a
76 # SIGHUP every time the ppp0 interface goes up, down, or is assigned a
77 # new IPv4 address. The SIGHUP will cause radvd to recognize that the
78 # ppp0 interface has changed and will adjust the advertisements

85 # If the IP address of ppp0 is assigned dynamically, be sure to set the
86 # lifetimes for this prefix to be small. Otherwise, hosts on your network
87 # may continue to use a prefix that no longer corresponds to the address
