5 # IPv6 as module will cause a CRASH if you try to unload it
7 tristate "The IPv6 protocol"
10 This is complemental support for the IP version 6.
11 You will still be able to do traditional IPv4 networking as well.
13 For general information about IPv6, see
14 <http://playground.sun.com/pub/ipng/html/ipng-main.html>.
15 For Linux IPv6 development information, see <http://www.linux-ipv6.org>.
16 For specific information about IPv6 under Linux, read the HOWTO at
17 <http://www.bieringer.de/linux/IPv6/>.
19 To compile this protocol support as a module, choose M here: the
20 module will be called ipv6.
23 bool "IPv6: Privacy Extensions support"
26 Privacy Extensions for Stateless Address Autoconfiguration in IPv6
27 support. With this option, additional periodically-alter
28 pseudo-random global-scope unicast address(es) will assigned to
31 We use our standard pseudo random algorithm to generate randomized
32 interface identifier, instead of one described in RFC 3041.
34 By default, kernel do not generate temporary addresses.
35 To use temporary addresses, do
37 echo 2 >/proc/sys/net/ipv6/conf/all/use_tempaddr
39 See <file:Documentation/networking/ip-sysctl.txt> for details.
41 config IPV6_ROUTER_PREF
42 bool "IPv6: Router Preference (RFC 4191) support"
45 Router Preference is an optional extension to the Router
46 Advertisement message to improve the ability of hosts
47 to pick more appropriate router, especially when the hosts
48 is placed in a multi-homed network.
52 config IPV6_ROUTE_INFO
53 bool "IPv6: Route Information (RFC 4191) support (EXPERIMENTAL)"
54 depends on IPV6_ROUTER_PREF && EXPERIMENTAL
56 This is experimental support of Route Information.
60 config IPV6_OPTIMISTIC_DAD
61 bool "IPv6: Enable RFC 4429 Optimistic DAD (EXPERIMENTAL)"
62 depends on IPV6 && EXPERIMENTAL
64 This is experimental support for optimistic Duplicate
65 Address Detection. It allows for autoconfigured addresses
66 to be used more quickly.
71 tristate "IPv6: AH transformation"
84 tristate "IPv6: ESP transformation"
95 Support for IPsec ESP.
100 tristate "IPv6: IPComp transformation"
103 select INET6_XFRM_TUNNEL
105 select CRYPTO_DEFLATE
107 Support for IP Payload Compression Protocol (IPComp) (RFC3173),
108 typically needed for IPsec.
113 tristate "IPv6: Mobility (EXPERIMENTAL)"
114 depends on IPV6 && EXPERIMENTAL
117 Support for IPv6 Mobility described in RFC 3775.
121 config INET6_XFRM_TUNNEL
130 config INET6_XFRM_MODE_TRANSPORT
131 tristate "IPv6: IPsec transport mode"
136 Support for IPsec transport mode.
140 config INET6_XFRM_MODE_TUNNEL
141 tristate "IPv6: IPsec tunnel mode"
146 Support for IPsec tunnel mode.
150 config INET6_XFRM_MODE_BEET
151 tristate "IPv6: IPsec BEET mode"
156 Support for IPsec BEET mode.
160 config INET6_XFRM_MODE_ROUTEOPTIMIZATION
161 tristate "IPv6: MIPv6 route optimization mode (EXPERIMENTAL)"
162 depends on IPV6 && EXPERIMENTAL
165 Support for MIPv6 route optimization mode.
168 tristate "IPv6: IPv6-in-IPv4 tunnel (SIT driver)"
173 Tunneling means encapsulating data of one protocol type within
174 another protocol and sending it over a channel that understands the
175 encapsulating protocol. This driver implements encapsulation of IPv6
176 into IPv4 packets. This is useful if you want to connect two IPv6
177 networks over an IPv4-only path.
179 Saying M here will produce a module called sit.ko. If unsure, say Y.
182 tristate "IPv6: IP-in-IPv6 tunnel (RFC2473)"
186 Support for IPv6-in-IPv6 and IPv4-in-IPv6 tunnels described in
191 config IPV6_MULTIPLE_TABLES
192 bool "IPv6: Multiple Routing Tables"
193 depends on IPV6 && EXPERIMENTAL
196 Support multiple routing tables.
199 bool "IPv6: source address based routing"
200 depends on IPV6_MULTIPLE_TABLES
202 Enable routing by source address or prefix.
204 The destination address is still the primary routing key, so mixing
205 normal and source prefix specific routes in the same routing table
206 may sometimes lead to unintended routing behavior. This can be
207 avoided by defining different routing tables for the normal and
208 source prefix specific routes.
