I read the following URL, and ping 224.0.0.1 succeeded.

Now, I want to use 224.201.201.1 as multicast address but queries are blocked.

I explain it in the following figure(Scenario 1: Compute host config).

  1. ping 224.0.0.1 from vm01 succeeds.
  2. ping 224.0.0.0/24(ex; 224.0.0.233) arrives at vm02 and vm03(use tcpdump)
  3. ping 224.201.201.1 not arives at qvbXXX (arrives at qbrXXX)

Who blocks 224.201.201.1? How does ping 224.201.201.1 succeed?
