  • Strange Multicast addresses

    Hello,
    I'm monitoring some strange multicast addresses on my network:
    224.2.127.254
    225.10.10.10

    ================
    225.10.10.10 FastEthernet0/0.21 1d10h 00:02:09 10.1.21.51 - WIN XP
    225.10.10.10 FastEthernet0/0.23 1w2d 00:02:14 10.1.23.51 - WIN XP
    224.2.127.254 FastEthernet0/0.20 5w0d 00:02:58 10.1.1.3 - WIN XP
    ================

    Can some one help with disabling of it?


    Thanks.

          it is blocked by cisco router already, but I'm trying to elliminate it from the source to free the cisco CPU from this issue
