Configuring the topology stability timer
When a station detects a topology change on the ring, it starts the topology stability timer and begins to
collect topology information to update its topology database. After the timer expires, the station checks
the validity of received topology information. If the information is valid, the station enters topology valid
state. If not, the station restarts the timer.

rpr timer stability stability-value 40 milliseconds by default.
Configuring the TC timers
The TC fast/slow timer defines the fast/slow interval at which TC frames are sent. When the ring
topology checksum changes, five TC frames are sent at the fast interval. When the ring topology is stable,
TC frames are sent at the slow interval.

4. Set the TC slow timer.
rpr timer tc-slow tc-slow-value 100 milliseconds by default.
Configuring the TP timers
The TP fast/slow timer defines the fast/slow interval at which TP frames are sent. When a station starts
initializing or detects a topology change, nine TP frames are sent at the fast interval. When the ring
topology is stable, the station begins to send TP frames at the slow interval.
