ifconfig uses an extended set of ioctls to configureīoth IPv4 and IPv6 network interfaces. The ifconfig command enables IPv6 interfaces and the tunneling module to be The 6to4relay command, the IPv4 address that you give with -a is displayed instead of 192.88.99.1.Ħto4relay does not report successful execution ofĭisplay any error messages that might be generated when you run these options. If you specify the -a option and an IPv4 address to IPv4 destination address of Relay Router=192.88.99.1Įxample 11–5 Status Display With a 6to4 Relay Router Specified If relay router support is enabled, 6to4relay displaysĦto4relay:6to4 Relay Router communication support is enabled This example shows the default for the Oracle Solaris implementation of IPv6.Ħto4relay:6to4 Relay Router communication support is disabledĮxample 11–4 Status Display With 6to4 Relay Router Support Enabled Without arguments, shows the current status of 6to4 relay router support. dĭisables support for tunneling to the 6to4 relay router, theįor more information, refer to the 6to4relay(1M)Įxample 11–3 Default Status Display of 6to4 Relay Router Support a IPv4-addressĮnables support for tunnels between the 6to4 router and aĦto4 relay router with the specified IPv4-address. The tunnel endpoint address is then set to 192.88.99.1, the default address for the anycast group of 6to4 relay routers. Syntax of 6to4relayĮnables support for tunnels between the 6to4 router and anĪnycast 6to4 relay router. Procedures in How to Configure a 6to4 Tunnel. If you decide to enable 6to4 relay router support, you can find the related For detailed information on 6to4 relay routers, refer to Considerations for Tunnels to a 6to4 Relay Router. Carefully consider the issues thatĪre involved in creating a tunnel to a 6to4 relay router before deploying Is disabled by default in Oracle Solaris. Use the 6to4relay command to enable the appropriate tunnel.īecause the use of relay routers is insecure, tunneling to a relay router If your 6to4-enabled site must exchange data with a native IPv6 site, you The 6to4 packets to the IPv6 network and ultimately, to the native IPv6 site. However, to transfer packets withĪ native, non-6to4 IPv6 site, the 6to4 router must establish a tunnel withĪ 6to4 relay router. You can change the policy table to give higher priority to site-localįor details about the ipaddrsel command, refer toĬommunication between isolated 6to4 sites. These addresses have the prefix fec0::/10. For example, site-localĪddresses are now deprecated in IPv6. You can add the deprecated address to the policy table. If you need to assign a higher priority to deprecated addresses, You can change the priority of ::ffff:0:0/96 to a higher If you want IPv4 addresses to take precedence over IPv6 addresses, If you want a particular source address to be used only inĬommunications with a particular destination address, you can add these addresses You can give higher priority to 6to4 addresses. If the system has an interface that is used for a 6to4 tunnel, You might want to modify the policy table under the following circumstances: If you do need to administer the policy table, you Under most instances, you do not need to change the IPv6 default address Reasons for Modifying the IPv6 Address Selection Given the selected IPv6 source address, the kernel also uses the IPv6 formatįor the destination address. Has a lower priority, particularly for packets going to an IPv6 destination. Therefore, by default, the kernel selects the global IPv6 address of the interfaceįor packets going to another IPv6 destination. Take precedence over 6to4 addresses ( 2002::/16) and IPv4 In this table, IPv6 prefixes ( ::1/128 and ::/0) You can find technical details for IPv6 address selection The following table lists the default address formats and their prioritiesįor the policy table. Table to perform destination address ordering and source address selectionįor an IPv6 packet header. The Oracle Solaris kernel uses the IPv6 default address selection policy The ipaddrsel command enables you to modify the IPv6 The text also describes modifications to existing commands This section describes commands that are added with the Oracle Solaris IPv6
