Another program you have heard much about in earlier chapters is gated. There are actually three different versions of this program. You can utilize gated for either unicast or multicast use, for either IPv4 or IPv6, or any combination of these you require—just make sure you have the correct version (see Table 5.2) for each. This routing daemon comes with many versions of Linux, though it might be on a second disk or among supplementary materials. If this is the daemon you decide to use and don’t have it, want the latest version, or need a capability that didn’t come with the version packaged with your distribution, go to www.gated.org or www.gated.merit.edu to obtain them.
