RP & restrict MC streams

[Shibu1978]

1. We are having the attached multicast setup  in our office.  Source are sitting in vlan 540 and receivers are in vlan 101. Souce multicast groups ranges are 225.0.1.0/24 & 226.0.1.0/24.

2. Source Unicast IPs are 10.20.12.0/24 and 10.20.13.0/24

Receivers Unicast IPs are  10.20.14.0/24 and 10.20.15.0/24

3. IP pim-sparse mode configured in all the above vlan interfaces

4. Now we have configured RP as the (HSRP) standby IP of the Vlan 540 (10.20.12.254)

Is this the right way of configuring RP ? any suggestions?

Also we need also to restict multicast streams 225 & 226 from receiving only from vlan 101 rest all vlan should be blocked.

Any suggestions

Hello Shibu,

best practice is to use a loopback for the RP address

then you can use anycast RP to provide fault tolerance.

this may be as easy as not enabling PIM on that other Vlans SVIs

or it may need some form of filtering

Hope to help

Hi Shibu,

While confiuring HSRP address as RP address may work, I am not sure if this is recommended. Can you explain what you are trying to acheive with HSRP address?. If you trying this design for RP redundancy, it is better to go for Anycast RP.

To deny mcast stream from other sources, use "ip pim accept-register" on RP.

HTH,
