Multicast routes are a similar concept to IP Routes, but as the name implies they are for Multicast addresses (which are class D), rather than standard IP Addresses (which are class A, B and C). For Unicast I would surmise you still use IP Routes.

There are two main ways to add a Multicast Route.

  1. Create a routing file in (CentOS) /etc/sysconfig/network-scripts/
  2. Add the route from the command line.
