Any one have an idea on how to suppress multicast flooding on a 2948G-L3. The switch is configured with 3 bridge groups, and 3 bvi interfaces. The problem is that multicast packets are flooded throughout the bridge group the multicast server is connected to. Below is a snippet of the running config:
ip multicast-routing ip dvmrp route-limit 20000 bridge irb ! int f1 no ip address bridge-group 2 ! int f2 no ip address bridge-group 2 ! int f3 no ip address bridge-group 3 ! int bvi 2 ip add 10.10.20.1 255.255.255.0 ip pim sparse-dense-mode ! int bvi 3 ip add 10.10.30.1 255.255.255.0 ip pim sparse-dense-mode ! bridge cmf bridge 2 proto ieee bridge 2 route ip bridge 3 proto ieee bridge 3 route ip etc Software version is: cat2948g-in-mz.120-14.W5.20.bin CGMP is not supported on the bvi interface (at least not with this software release). CMF (Constrained Multicast Flooding) should do the trick, but doesn't appear to be working as expected. The flooding happens regardless of whether or not any host registers interest in receiving the multicast group. Multicast routing is working fine, and only registered hosts receive the multicast traffic, i.e flooding does not occur on the bridge group that the multicast server is not connected to. Any ideas will be greatly appreciated.
