RP mode – Select asm (Any-Source Multicast) or bidir (Bidirectional PIM) mode.
When you choose asm, the BIDIR related fields are not enabled.
The asm RP mode supports up to 4 RPs.
The bidir mode supports up to 2 RPs. An error message is displayed if the BIDIR configuration indicates that more than 2 RPs are used.
After brownfield migration, only 2 RPs are supported in the migrated fabric. An error message is displayed when you click
Save & Deploy after changing the RP count to 4.
If an RP is down or deleted from the fabric, this RP cannot be replaced by another spine as Easy Fabric does not remember
the configuration of a removed switch. Easy Fabric uses a specific scheme to generate RP configuration for BIDIR. Therefore,
the generated Bidir configuration will not work with the brownfield imported configuration. After brownfield migration, if
you change the RP count or add new spine or leaf switches, you should manually configure the PIM-BIDIR feature. If a manual
configuration is required, a warning message is displayed after you click Save & Deploy. For more information, see Manually Adding PIM-BIDIR Configuration for Leaf or Spine Post Brownfield Migration.
You can also modify a brownfield imported BIDIR configuration to use the configuration generated by Fabric Builder. For more information, see Changing a Brownfield Imported BIDIR Configuration.
