The rpf-frr clone join command enables the function to clone user-to-source multicast Join messages.
The undo rpf-frr clone join command disables the function.
By default, the function to clone user-to-source multicast Join messages is disabled.
| Parameter | Description | Value |
|---|---|---|
| source-address |
Clones a user-to-source multicast Join message to two specified Join messages. source-address2 must be different from source-address and source-address1. |
The values are Class A, B, or C IP addresses, in dotted decimal notation, but cannot be IP addresses on the segment 0.0.0.0/8 or 127.0.0.0/8. |
| to source-address1 |
Clones a source-address1. |
The values are Class A, B, or C IP addresses, in dotted decimal notation, but cannot be IP addresses on the segment 0.0.0.0/8 or 127.0.0.0/8. |
| and source-address2 |
Clones a source-address2. |
The values are Class A, B, or C IP addresses, in dotted decimal notation, but cannot be IP addresses on the segment 0.0.0.0/8 or 127.0.0.0/8. |
| masklen mask-length |
Specifies the mask length for a multicast source address. |
The value is an integer ranging from 1 to 32. |
Usage Scenario
If dual feed and selective receiving is needed to improve fault convergence performance in multicast service scenarios, multicast source cloning-based PIM FRR can be deployed to protect services. To enable the function to clone user-to-source multicast Join message, run the rpf-frr clone join command on the user-side multicast device, so that multicast traffic of the cloned multicast sources can also be sent to users.
Prerequisites
PIM FRR has been enabled using the rpf-frr command.
Precautions
If s1 is set to the same value as , PIM FRR traffic switchback must be disabled. Otherwise, multicast traffic will be repeatedly switched between the primary and backup paths, causing service loss.
Only the NetEngine 8000 F1A supports this command.
