| 114 | Support for IPv6 Identifier Locator Addressing (ILA). |
| 115 | |
| 116 | ILA is a mechanism to do network virtualization without |

| 118 | IPv6 address into a 64 bit locator and 64 bit identifier. The |
| 119 | identifier is the identity of an entity in communication |
| 120 | ("who") and the locator expresses the location of the |
| 121 | entity ("where"). |
| 122 | |
| 123 | ILA can be configured using the "encap ila" option with |
| 124 | "ip -6 route" command. ILA is described in |
| 125 | https://tools.ietf.org/html/draft-herbert-nvo3-ila-00. |

| 268 | Enable routing by source address or prefix. |
| 269 | |
| 270 | The destination address is still the primary routing key, so mixing |
| 271 | normal and source prefix specific routes in the same routing table |
| 272 | may sometimes lead to unintended routing behavior. This can be |
| 273 | avoided by defining different routing tables for the normal and |
| 274 | source prefix specific routes. |

| 290 | Normally, a multicast router runs a userspace daemon and decides |
| 291 | what to do with a multicast packet based on the source and |
| 292 | destination addresses. If you say Y here, the multicast router |
| 293 | will also be able to take interfaces and packet marks into |

| 295 | simultaneously, each one handling a single table. |
