PRIMECLUSTER Global Link Services Configuration and Administration Guide: Redundant Line Control Function 4.1 (for Solaris(TM) Operating System)

3.2.2.2 System setup in Fast switching mode

• When using an IPv4 address, define in the /etc/inet/hosts file the host names (host names to be attached to virtual IP, monitored host names to be specified in monitoring destination information, etc.) to be specified in environment definitions of Redundant Line Control function. These host names must be specified in the /etc/inet/hosts file even if no host names but IP addresses are directly specified in environment definitions.
• If an IPv6 address is used, define the IPv6 address and a host name in /etc/inet/ipnodes file.
• When using an IPv4 address, define a configured physical interface to use in IPv4 before defining a virtual interface. (Check whether or not an /etc/hostname.interface file exists. If not, create it and reboot the system.)
• When using an IPv6 address, define a configured physical interface to use in IPv6 before defining a virtual interface. (Check whether or not an /etc/hostname6.interface file exists. If not, create it and reboot the system. When creating a /etc/hostname6.interface file, make sure it is an empty file.)
• If IPv6 address is used, it is recommended to setup at least two Solaris servers running in Fast switching mode as IPv6 routers just in case an IPv6 router fails and communication cannot be achieved using a site local address. Note that if configuring IPv6 router for multiple servers, make sure these servers use the same prefix information for the virtual interface configured in /etc/inet/ndpd.conf.
  An example of setting a /etc/inet/ndpd.conf file when using a Solaris server as an IPv6 router is shown below. (See a Solaris manual for the detail of a /etc/inet/ndpd.conf file.)

ifdefault AdvSendAdvertisements true  # Every interface sends a router advertisement.
prefix fec0:1::0/64 sha0              # sha0 sends "Prefix fec0:1::0/64".
