I have a network architecture of 2 C5500 with RSM/NFFC2 and 4 VLAN's directly attached on a delta configuration: switch dual attached with STP and HSRP redundancy.
I would like to enable CGMP + IGMP snooping to constrain multicats at layer 2 only and not route any multicast traffic between the VLAN's.
Since I need to enable multicast routing on the RSM on all the VLAN interfaces where I will use CGMP, is there a way not to route traffic while still using CGMP?
Here is the configuration:
Enable the IP multicasting (global command):
Enable each interface running CGMP (interface mode):
ip pim sparse-mode
Thanks for your help,
