Solaris 8 Installation Supplement

Default Router Specification During System Identification

The system identification utilities were updated in the Solaris 8 4/01 software release to automatically attempt to determine the default router during installation.

The system identification utilities automatically attempt to determine the default router by checking for a sysidcfg file. If the utilities cannot find the needed information in the sysidcfg file, the utilities query route broadcasts. If the default router information is not available from route broadcasts, the system identification utilities attempt to get the information from the Dynamic Host Configuration Protocol (DHCP) server, if the system is being configured with DHCP.

If you are installing by using the Solaris Web Start 3.0 installation method and the installation software cannot detect a default router, you are prompted to specify the default router.

If you are installing by using the Interactive Installation Program on the Solaris 8 1 of 2 CD, the default router must be detectable or you must specify it in the sysidcfg file. The Interactive Installation Program does not prompt you to specify a default router.

Preconfiguring the Default Router With the sysidcfg File

This section supplements “Guidelines for Preconfiguring With the sysidcfg File” in Solaris 8 Advanced Installation Guide.

The sysidcfg file preconfigures system identification information through a set of keywords that specify information you want to preconfigure. The default_route parameter for the network_interface keyword allows the specification of a default router during the Solaris installation. The new parameter is described in Table 2–1.

Table 2–1 network_interface Keyword

Configuration Information 

Platform 

Keywords 

Where to Find Values/Example 

Network interface, host name, default router, Internet Protocol (IP) address, netmask, DHCP, IPv6 

All 

network_interface=NONE, PRIMARY, or value

  
    If DHCP is to be used, specify: {dhcp protocol_ipv6=yes_or_no}

network_interface=primary {dhcp protocol_ipv6=yes}

    If DHCP is not to be used, specify: {hostname=host_name default_route=ip_address ip_address=ip_address netmask=netmask protocol_ipv6=yes_or_no}

network_interface=le0 {hostname=feron default_route=129.146.88.1 ip_address=129.146.88.210 netmask=255.255.0.0 protocol_ipv6=no}

Note –

Choose only one value for network_interface. Include any combination or none of the hostname, ip_address, and netmask keywords, as needed. If you do not use any of these keywords, omit the curly braces ({}).

Note –

If DHCP is not to be used, you do not need to specify protocol_ipv6 and default_route. If the software cannot autodetect a default router, the Web Start 3.0 installation software prompts you to specify one.
