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.
61 tristate "IPv6: AH transformation"
74 tristate "IPv6: ESP transformation"
84 Support for IPsec ESP.
89 tristate "IPv6: IPComp transformation"
92 select INET6_XFRM_TUNNEL
96 Support for IP Payload Compression Protocol (IPComp) (RFC3173),
97 typically needed for IPsec.
102 bool "IPv6: Mobility (EXPERIMENTAL)"
103 depends on IPV6 && EXPERIMENTAL
106 Support for IPv6 Mobility described in RFC 3775.
110 config INET6_XFRM_TUNNEL
119 config INET6_XFRM_MODE_TRANSPORT
120 tristate "IPv6: IPsec transport mode"
125 Support for IPsec transport mode.
129 config INET6_XFRM_MODE_TUNNEL
130 tristate "IPv6: IPsec tunnel mode"
135 Support for IPsec tunnel mode.
139 config INET6_XFRM_MODE_BEET
140 tristate "IPv6: IPsec BEET mode"
145 Support for IPsec BEET mode.
149 config INET6_XFRM_MODE_ROUTEOPTIMIZATION
150 tristate "IPv6: MIPv6 route optimization mode (EXPERIMENTAL)"
151 depends on IPV6 && EXPERIMENTAL
154 Support for MIPv6 route optimization mode.
157 tristate "IPv6: IPv6-in-IPv4 tunnel (SIT driver)"
161 Tunneling means encapsulating data of one protocol type within
162 another protocol and sending it over a channel that understands the
163 encapsulating protocol. This driver implements encapsulation of IPv6
164 into IPv4 packets. This is useful if you want to connect two IPv6
165 networks over an IPv4-only path.
167 Saying M here will produce a module called sit.ko. If unsure, say Y.
170 tristate "IPv6: IPv6-in-IPv6 tunnel"
174 Support for IPv6-in-IPv6 tunnels described in RFC 2473.
178 config IPV6_MULTIPLE_TABLES
179 bool "IPv6: Multiple Routing Tables"
180 depends on IPV6 && EXPERIMENTAL
183 Support multiple routing tables.
186 bool "IPv6: source address based routing"
187 depends on IPV6_MULTIPLE_TABLES
189 Enable routing by source address or prefix.
191 The destination address is still the primary routing key, so mixing
192 normal and source prefix specific routes in the same routing table
193 may sometimes lead to unintended routing behavior. This can be
194 avoided by defining different routing tables for the normal and
195 source prefix specific routes.
199 config IPV6_ROUTE_FWMARK
200 bool "IPv6: use netfilter MARK value as routing key"
201 depends on IPV6_MULTIPLE_TABLES && NETFILTER
203 If you say Y here, you will be able to specify different routes for
204 packets with different mark values (see iptables(8), MARK target).
