IPV4 Multipathing


  • Multipathing provides failure detection, repair detection, and load balancing of outbound traffic when data is flowing to more than one destination.

  • To run multipathing the system must have more than one interface, be running Solaris 8 10/00 or later, have a test address configured for each interface using multipathing, have each interface belong to the same multicast group and have a unique Ethernet address.

  • in.mpathd reads /etc/default/mpathd on startup. It carries out failure and repair detection by probing test addresses on each interface and by monitoring the internal IFF_RUNNING flag.

  • To configure hme0 with the multicast group ultra , edit the /etc/hostname.hme0 file:

     ultra10 netmask + broadcast + group ultra up \ addif ultra10_mp deprecated netmask + broadcast + -failover up 

    Or use the command line:

     # ifconfig hme0 group ultra # ifconfig hme0 addif ultra10_mp deprecated netmask + broadcast + \  -failover up 

    The deprecated and -failover options make it a test address.
