| config IPV6 |
| tristate "The IPv6 protocol" |
| default m |
| ---help--- |
| This is complemental support for the IP version 6. |
| You will still be able to do traditional IPv4 networking as well. |
| |
| For general information about IPv6, see |
| <http://playground.sun.com/pub/ipng/html/ipng-main.html>. |
| For Linux IPv6 development information, see <http://www.linux-ipv6.org>. |
| For specific information about IPv6 under Linux, read the HOWTO at |
| <http://www.bieringer.de/linux/IPv6/>. |
| |
| To compile this protocol support as a module, choose M here: the |
| module will be called ipv6. |

| config IPV6_PRIVACY |
| bool "IPv6: Privacy Extensions support" |
| depends on IPV6 |
| ---help--- |
| Privacy Extensions for Stateless Address Autoconfiguration in IPv6 |
| support. With this option, additional periodically-alter |
| pseudo-random global-scope unicast address(es) will assigned to |
| your interface(s). |
| |
| We use our standard pseudo random algorithm to generate randomized |
| interface identifier, instead of one described in RFC 3041. |
| |
| By default, kernel do not generate temporary addresses. |
| To use temporary addresses, do |
| |
| echo 2 >/proc/sys/net/ipv6/conf/all/use_tempaddr |
| |
| See <file:Documentation/networking/ip-sysctl.txt> for details. |

| config IPV6_SIT |
| tristate "IPv6: IPv6-in-IPv4 tunnel (SIT driver)" |
| depends on IPV6 |
| select INET_TUNNEL |
| default y |
| ---help--- |
| Tunneling means encapsulating data of one protocol type within |
| another protocol and sending it over a channel that understands the |
| encapsulating protocol. This driver implements encapsulation of IPv6 |
| into IPv4 packets. This is useful if you want to connect two IPv6 |
| networks over an IPv4-only path. |
| |
| Saying M here will produce a module called sit.ko. If unsure, say Y. |
| |
| config IPV6_TUNNEL |
| tristate "IPv6: IPv6-in-IPv6 tunnel" |

| bool "IPv6: source address based routing" |
| depends on IPV6_MULTIPLE_TABLES |
| ---help--- |
| Enable routing by source address or prefix. |
| |
| The destination address is still the primary routing key, so mixing |
| normal and source prefix specific routes in the same routing table |
| may sometimes lead to unintended routing behavior. This can be |
| avoided by defining different routing tables for the normal and |
| source prefix specific routes. |
| |
| If unsure, say N. |
