+	  Support for IPv6 Identifier Locator Addressing (ILA).
+
+	  ILA is a mechanism to do network virtualization without

+	  IPv6 address into a 64 bit locator and 64 bit identifier. The
+	  identifier is the identity of an entity in communication
+	  ("who") and the locator expresses the location of the
+	  entity ("where").
+
+	  ILA can be configured using the "encap ila" option with
+	  "ip -6 route" command. ILA is described in
