 .It Li icmp6.nodeinfo
 The variable enables, or disables, kernel support for
 ICMPv6 node information query/reply.
+.It Li icmp6.errppslimit
+The variable specifies the maximum number of outgoing ICMPv6 error messages,
+per second.
+ICMPv6 error messages that exceeded the value is subject to rate limitation
+and will not go out from the node.
+.It Li icmp6.nd6_maxnudhint
+IPv6 neighbor discovery permits upper layer protocols to supply reachability
+hints, to avoid unnecessary neighbor discovery exchanges.
+The variable defines the number of consecutive hints the neighbor discovery
+layer will take.
+For example, by setting the variable to 3, neighbor discovery layer
+will take 3 consecutive hints in maximum.
+After receiving 3 hints, neighbor discovery layer will perform
+normal neighbor discovery process.
