Hi All, I am planning to implement Multicasting in my network where we have redundancy at every place. We have two mcast stream from group1 & group2 which has to be seen by only group1 & group2 users repectively. Grou1 user shud not see stream from group2 & vice versa. I am planning to use Static RP with sparse-dense mode config but how can I achieve restriction as i mentioned and redundancy if one router goes down other shud forward & act as RP. I am running HSRP bw routers. Here is the block diagram from your understanding.
If I've understood correctly you want to do the following:
about avoiding Group1's users to be able to join Group2 multicast group and viceversa.
If you can put them in two different IP subnets you can use the interface command ip igmp access-group : using two different acls you can deny the two groups on the two interfaces.
Redundancy of RPs: you should consider to use Auto-RP or Bootstrap protocol and the anycast RP. However, if you have only two routers you could play with ACLs in the ip pim rp-address if your multicast addresses are different enough.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
