5. Auto-RP dynamic election RP

The following rules are required to configure Auto-RP

1. PIM mode should be configured as sparse-dense mode (when Sparse mode does not work, you can work in Dense mode to start backup redundancy)

2. CRP and MA usually use loop backports, which need to be entered into IGP.

3. The loop loop of MA should also be configured in sparese-dense mode.

Let's talk about R1 configured as CRP,R2 and configured as MA.
