Can I use Auto-RP with Cisco switches and HP switches?

[JustTakeTheFirstStep]

I don't know much about multicast.

Perhaps the HP switch has multicast enabled.
None of us have access to the HP switch to see the configuration.

The new video stream server and TVs will be connected to the Cisco switch.
Therefore, I need to configure multicast on the Cisco switch.

I think Auto-RP is a good technology.
If I am already using RP on HP switches, can I use Auto-RP on Cisco switches?

Any ideas?

Hello @JustTakeTheFirstStep 

Thanks for that draw attached to your question.

If the HP switch is already using a static RP or PIM-BSR for multicast, you should match its RP configuration on the Cisco switch rather than using Auto-RP, as Auto-RP is Cisco-proprietary and may not be supported by HP.

To ensure multicast works on the Cisco switch for the video stream server and TVs, enable ip multicast-routing, configure PIM Sparse Mode on the VLAN interfaces, and either manually set the same RP as the HP switch (ip pim rp-add <rendez-vous point IP>) or use PIM-BSR if HP supports it. If multicast traffic does not need to flow between the Cisco and HP switches, you can configure Auto-RP on the Cisco switch independently by setting it as an RP (ip pim send-rp-announce and  ippim send-rp-discovery on a loopback interface), but interoperability with HP should be verified first...

Hello
As stated BSR is non proprietary , but simple static RP is applicable based on your ASM topology, unless you that you which to have RP resiliency then use BSR would be preferable over static RP, however you could negate RP altogether by using SSM

I created an SVI according to the guide to use sparse-mode.
However, I did not use “ip routing” on the switch.
Do I need to do “ip routing” to use sparse-mode on the 2960 switch?

Hello
HP/Aruba (mainly aruba) will support Static RP or BSR but it will NOT support auto-rp as that is Cisco propitiatory.
