The state-refresh-ttl command sets the TTL value for sending PIM State-Refresh messages.
The undo state-refresh-ttl command restores the default value of the TTL.
| Parameter | Description | Value |
|---|---|---|
| ttl-value | Specifies the minimum TTL value of the PIM state refresh message sent by an interface. | The value is an integer that ranges from 1 to 255. |
By default, the TTL value for sending PIM State-Refresh messages is 255.
The command is applicable to PIM-DM networks.
After receiving a State-Refresh message, the FW decreases the value of the TTL in the message by 1, and then sends the message to the downstream FW until the value of the TTL becomes 0. If the scale of the network is small, the message is delivered in a loop.
You can use the state-refresh-ttl command to set the value of the TTL according to the scale of the network.
