The rpf-frr clone source command enables the function to clone the traffic of a multicast source.
The undo rpf-frr clone source command disables the function.
By default, the function to clone the traffic of a multicast source is disabled.
| Parameter | Description | Value |
|---|---|---|
| source-address |
Specifies a specified multicast source. |
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 the traffic of a multicast source to the traffic of a specified multicast source source1. |
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 the traffic of an original multicast source to the traffic of another specified multicast source. s2 must be different from s and s1. |
The value is a Class A, B, or C IP address, in dotted decimal notation, but cannot be an IP address 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 the traffic of a multicast source, run the rpf-frr clone source command on the multicast source-side device (root PE).
Prerequisites
PIM FRR has been enabled using the rpf-frr command.
Precautions
The s, s1, and s2 cannot be the same.
A source address supports a maximum of 2 cloned source addresses.Only the NetEngine 8000 F1A supports this command.
