+# Note: All of the following parameters have default values defined

+#   IPv6 prefixes are configured in this part. However, rtadvd
+#   automatically learns appropriate prefixes from the kernel's routing
+#   table and advertises the prefixes, so you don't have to configure
+#   this part, either.
+#   If you don't want the automatic advertisement, invoke rtadvd with
+#   the -s option and configure this part by hand.
