The multicast static-frr command enables multicast FRR for a source-specific multicast group.
The undo multicast static-frr command disables multicast FRR.
By default, multicast FRR is disabled.

| Parameter | Description | Value |
|---|---|---|
| group group-address |
Specifies a multicast group address. |
The value ranges from 224.0.0.0 to 239.255.255.255, in dotted decimal notation. |
| mask |
IP address mask. |
- |
| mask-value |
Specifies the mask of a multicast group address. |
The value is in dotted decimal notation. |
| mask-length |
Specifies the mask length of a multicast group address. |
The value is an integer ranging from 4 to 32. |
| vpn-instance vpn-instance-name |
Specifies a VPN instance name. |
The value is a string of 1 to 31 case-sensitive characters. |
| source source-address |
Specifies a multicast source address. |
The value is in dotted decimal notation. |
Usage Scenario
If both primary and secondary links are available, the device permits the copy of the same (S, G) flow on the primary link but discards that on the secondary link. However, if the primary link fails, the device switches to the secondary link and permits the copy on the secondary link. Multicast FRR enables the device to rapidly implement such a service switchover. To enable multicast FRR for a source-specific group, run the multicast static-frr command.
Precautions
A maximum of 2000 protected multicast source groups can be configured.
