3.8.5 Setting the TTL Value of a State-Refresh Message

Context
When receiving a State-Refresh message, an S9300 subtracts 1 from the TTL value and forwards
the value to a downstream S9300 until the TTL value becomes 0. On a small scale network,
State-Refresh messages are transmitted circularly. To effectively control the transmission range,
you need to set a proper TTL value according to the scale of the network.
