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.
25 bool "IPv6: Privacy Extensions support"
27 Privacy Extensions for Stateless Address Autoconfiguration in IPv6
28 support. With this option, additional periodically-alter
29 pseudo-random global-scope unicast address(es) will assigned to
32 We use our standard pseudo random algorithm to generate randomized
33 interface identifier, instead of one described in RFC 3041.
35 By default, kernel do not generate temporary addresses.
36 To use temporary addresses, do
38 echo 2 >/proc/sys/net/ipv6/conf/all/use_tempaddr
40 See <file:Documentation/networking/ip-sysctl.txt> for details.
42 config IPV6_ROUTER_PREF
43 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 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"
83 tristate "IPv6: ESP transformation"
93 Support for IPsec ESP.
98 tristate "IPv6: IPComp transformation"
100 select INET6_XFRM_TUNNEL
102 select CRYPTO_DEFLATE
104 Support for IP Payload Compression Protocol (IPComp) (RFC3173),
105 typically needed for IPsec.
110 tristate "IPv6: Mobility (EXPERIMENTAL)"
111 depends on EXPERIMENTAL
114 Support for IPv6 Mobility described in RFC 3775.
118 config INET6_XFRM_TUNNEL
127 config INET6_XFRM_MODE_TRANSPORT
128 tristate "IPv6: IPsec transport mode"
132 Support for IPsec transport mode.
136 config INET6_XFRM_MODE_TUNNEL
137 tristate "IPv6: IPsec tunnel mode"
141 Support for IPsec tunnel mode.
145 config INET6_XFRM_MODE_BEET
146 tristate "IPv6: IPsec BEET mode"
150 Support for IPsec BEET mode.
154 config INET6_XFRM_MODE_ROUTEOPTIMIZATION
155 tristate "IPv6: MIPv6 route optimization mode (EXPERIMENTAL)"
156 depends on EXPERIMENTAL
159 Support for MIPv6 route optimization mode.
162 tristate "IPv6: IPv6-in-IPv4 tunnel (SIT driver)"
164 select IPV6_NDISC_NODETYPE
167 Tunneling means encapsulating data of one protocol type within
168 another protocol and sending it over a channel that understands the
169 encapsulating protocol. This driver implements encapsulation of IPv6
170 into IPv4 packets. This is useful if you want to connect two IPv6
171 networks over an IPv4-only path.
173 Saying M here will produce a module called sit.ko. If unsure, say Y.
175 config IPV6_NDISC_NODETYPE
179 tristate "IPv6: IP-in-IPv6 tunnel (RFC2473)"
182 Support for IPv6-in-IPv6 and IPv4-in-IPv6 tunnels described in
187 config IPV6_MULTIPLE_TABLES
188 bool "IPv6: Multiple Routing Tables"
189 depends on EXPERIMENTAL
192 Support multiple routing tables.
195 bool "IPv6: source address based routing"
196 depends on IPV6_MULTIPLE_TABLES
198 Enable routing by source address or prefix.
200 The destination address is still the primary routing key, so mixing
201 normal and source prefix specific routes in the same routing table
202 may sometimes lead to unintended routing behavior. This can be
203 avoided by defining different routing tables for the normal and
204 source prefix specific routes.
209 bool "IPv6: multicast routing (EXPERIMENTAL)"
210 depends on IPV6 && EXPERIMENTAL
212 Experimental support for IPv6 multicast forwarding.
216 bool "IPv6: PIM-SM version 2 support (EXPERIMENTAL)"
217 depends on IPV6_MROUTE
219 Support for IPv6 PIM multicast routing protocol PIM-SMv2.
