Hello John
From a network engineering perspective, it seems like you’re dealing with a high volume of multicast traffic, which is causing some issues with your Aruba VSX L3 switches. You’re right in considering MSDP as a potential solution to your problem.
MSDP is typically used in conjunction with PIM-SM to share information about multicast sources between different multicast domains. This could potentially help you manage the high volume of multicast traffic in your network more effectively.
However, it’s important to note that implementing MSDP should be done with caution. It’s a complex protocol and it could potentially cause more issues if not configured correctly. First, you should thoroughly understand how MSDP works and how it will interact with your existing PIM and BSR setup. Also, consider the potential impact on your network’s performance and stability, especially given your concern about reaching the limit of 32k multicast routes per core.
I would recommend testing this setup in a controlled environment before deploying it in your live network. You might also want to consider reaching out to your vendor’s technical support team to help you through this process.
Remember, network changes of this magnitude should always be approached with a detailed plan, including a rollback strategy in case things don’t go as expected.
I hope this has been helpful!
