If a parameter 16 is not specified the default value is used. 17 18 The parameters are as follows: 19 20 disable 21 22 Specifies whether to load the IPv6 module, but disable all 23 its functionality. This might be used when another module 24 has a dependency on the IPv6 module being loaded, but no 25 IPv6 addresses or operations are desired. 26 27 The possible values and their effects are: 28 29 0 30 IPv6 is enabled. 31 32 This is the default value. 33 34 1 35 IPv6 is disabled. 36 37 No IPv6 addresses will be added to interfaces, and 38 it will not be possible to open an IPv6 socket. 39 40 A reboot is required to enable IPv6. 41 42 autoconf 43 44 Specifies whether to enable IPv6 address autoconfiguration 45 on all interfaces. This might be used when one does not wish 46 for addresses to be automatically generated from prefixes 47 received in Router Advertisements. 48 49 The possible values and their effects are: 50 51 0 52 IPv6 address autoconfiguration is disabled on all interfaces. 53 54 Only the IPv6 loopback address (::1) and link-local addresses 55 will be added to interfaces. 56 57 1 58 IPv6 address autoconfiguration is enabled on all interfaces. 59 60 This is the default value. 61 62 disable_ipv6 63 64 Specifies whether to disable IPv6 on all interfaces. 65 This might be used when no IPv6 addresses are desired. 66 67 The possible values and their effects are: 68 69 0 70 IPv6 is enabled on all interfaces. 71 72 This is the default value. 73 74 1 75 IPv6 is disabled on all interfaces. 76 77 No IPv6 addresses will be added to interfaces. 78
