The peer minimum-ttl command sets the TTL threshold of the Source Active (SA) message encapsulated with multicast data that is forwarded to the specific peer.
The undo peer minimum-ttl command restores the default configuration.
| Parameter | Description | Value |
|---|---|---|
| peer-address | Specifies address of an MSDP peer to which the TTL limit applies. | The address is in dotted decimal notation. |
| ttl | Indicates the value of the TTL threshold. | The value is an integer that ranges from 0 to 255. |
By default, the value of the TTL threshold is 0.
MSDP peers set up TCP connections to transmit SA messages to each other. The peer minimum-ttl command is used to limit the number of multicast data packets encapsulated in the SA message.
After the TTL threshold is set for a specified peer, a FW checks the TTL of a multicast data packet before encapsulating the multicast data packet in an SA message. Only the multicast data packet with the TTL greater than the threshold is encapsulated in an SA message and sent to the peer of a FW.
