Hi Group,

I am testing the multicast help-map, and it found the broadcast haven't
mapped to multicast, can anybody give me a hints?

Broadcast address 192.168.1.255
Translated to 233.233.233.233

The following is the interface config, I have confirmed that broadcast
traffics get arrived this router:

      interface FastEthernet0/0
       ip address 192.168.1.1 255.255.255.0
       ip directed-broadcast
       ip router isis DOG
       ip pim sparse-dense-mode
       ip multicast helper-map broadcast 233.233.233.233 144 ttl 15
       no ip mroute-cache

      R6#sh access-l 144
      Extended IP access list 144
          permit udp any any eq 3000
          deny udp any any

      R6#sh ip mro ac
      Active IP Multicast Sources - sending >= 4 kbps

      R6#sh ip mro co
      IP Multicast Statistics
      8 routes using 3584 bytes of memory
      5 groups, 0.60 average sources per group
      Forwarding Counts: Pkt Count/Pkts per second/Avg Pkt Size/Kilobits
per second
      Other counts: Total/RPF failed/Other drops(OIF-null, rate-limit etc)

      Group: 233.233.233.233, Source count: 0, Packets forwarded: 0,
Packets received: 0

As you can see above, my problem is the broadcast haven't translated to
multicast, and the group 233.233.233.233 haven't got any packet even
destination joins, the broadcast traffic are generating around 20k bit/s.

Thx,
