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"
94 Support for IPsec ESP.
99 tristate "IPv6: IPComp transformation"
102 select INET6_XFRM_TUNNEL
104 select CRYPTO_DEFLATE
106 Support for IP Payload Compression Protocol (IPComp) (RFC3173),
107 typically needed for IPsec.
112 tristate "IPv6: Mobility (EXPERIMENTAL)"
113 depends on IPV6 && EXPERIMENTAL
116 Support for IPv6 Mobility described in RFC 3775.
120 config INET6_XFRM_TUNNEL
129 config INET6_XFRM_MODE_TRANSPORT
130 tristate "IPv6: IPsec transport mode"
135 Support for IPsec transport mode.
139 config INET6_XFRM_MODE_TUNNEL
140 tristate "IPv6: IPsec tunnel mode"
145 Support for IPsec tunnel mode.
149 config INET6_XFRM_MODE_BEET
150 tristate "IPv6: IPsec BEET mode"
155 Support for IPsec BEET mode.
159 config INET6_XFRM_MODE_ROUTEOPTIMIZATION
160 tristate "IPv6: MIPv6 route optimization mode (EXPERIMENTAL)"
161 depends on IPV6 && EXPERIMENTAL
164 Support for MIPv6 route optimization mode.
167 tristate "IPv6: IPv6-in-IPv4 tunnel (SIT driver)"
172 Tunneling means encapsulating data of one protocol type within
173 another protocol and sending it over a channel that understands the
174 encapsulating protocol. This driver implements encapsulation of IPv6
175 into IPv4 packets. This is useful if you want to connect two IPv6
176 networks over an IPv4-only path.
178 Saying M here will produce a module called sit.ko. If unsure, say Y.
181 tristate "IPv6: IPv6-in-IPv6 tunnel"
185 Support for IPv6-in-IPv6 tunnels described in RFC 2473.
189 config IPV6_MULTIPLE_TABLES
190 bool "IPv6: Multiple Routing Tables"
191 depends on IPV6 && EXPERIMENTAL
194 Support multiple routing tables.
197 bool "IPv6: source address based routing"
198 depends on IPV6_MULTIPLE_TABLES
200 Enable routing by source address or prefix.
202 The destination address is still the primary routing key, so mixing
203 normal and source prefix specific routes in the same routing table
204 may sometimes lead to unintended routing behavior. This can be
205 avoided by defining different routing tables for the normal and
206 source prefix specific routes.
