Hello Istvan

Thanks for sharing that information with us, it is quite useful. I will let Rene know so he can consider if any changes or clarifications are necessary on the lesson.

Thanks again!

Hi @ReneMolenaar @lagapides

What will take precedence if we enable both auto-RP and BSR in the network?

Hello Nipun

In a multicast network, if both Auto-RP and BSR are enabled, BSR will take precedence over Auto-RP. BSR is considered a more advanced and scalable solution for PIM-SM group-to-RP mapping compared to Auto-RP.

Remember that BSR is an open standard that is defined in RFC 5059 and is part of the PIM-SM standard, while Auto-RP is a Cisco proprietary mechanism. BSR is generally preferred in multi-vendor environments or in larger networks due to its better scalability and improved functionality.

However, it is generally not recommended to have both mechanisms enabled at the same time, as this may lead to inconsistencies in group-to-RP mappings and potential routing issues. It is better to choose one of the mechanisms and configure it consistently across the network.

I hope this has been helpful!
