| 102 | |
| 103 | ILA is a mechanism to do network virtualization without |

| 105 | IPv6 address into a 64 bit locator and 64 bit identifier. The |
| 106 | identifier is the identity of an entity in communication |
| 107 | ("who") and the locator expresses the location of the |
| 108 | entity ("where"). |
| 109 | |
| 110 | ILA can be configured using the "encap ila" option with |
| 111 | "ip -6 route" command. ILA is described in |
| 112 | https://tools.ietf.org/html/draft-herbert-nvo3-ila-00. |
