Configuring Evpn Timers Per Ethernet Segment And Ce Flushing Mechanism - Cisco ASR 9000 Series Configuration Manuallines

Configuring EVPN Timers Per Ethernet Segment and CE flushing mechanism

Example:
RP/0/RSP0/CPU0:router(config-evpn)# timers flushagain 40
Configures global EVPN timers.
• Flush-again timer (for AApS only): When a MAC flush is sent, usually at the end of the programming timer expiration,
a flush-again timer is started for the flush-again timer value. When it expires, another MAC flush message (MVRP
or STP-TCN) is sent to the CE. This timer can be configured per segment-interface.
Range: 0 to 120 seconds, 0 means disabled
Default: 60 seconds
• Peering timer: Once all conditions are met to advertise to BGP, the PE waits for the peering timer value before
advertising its RT, ESI and, Local MAC if it is Single-Home.
Range: 0 to 300 seconds, 0 means disabled
Default: 45 seconds
• Programming timer: Indicated time required by the HW to apply the carving results. At the end of the programming
timer expiration, the next Ethernet Segment route object will be processed.
Range: 0 to 100000 microseconds
Default: 1500 microseconds
• Recovery timer (for AApS only): Once the interface is up, the PE waits for the recovery timer value in order to allow
the CE running STP protocol to converge. This timer can be configured per segment-interface.
Range: 20 to 3600 seconds
Default: 20 seconds
Note Changing timers is only useful for scale configurations.
Step 4
Use the commit or end command.
commit - Saves the configuration changes and remains within the configuration session.
end - Prompts user to take one of these actions:
• Yes - Saves configuration changes and exits the configuration session.
• No - Exits the configuration session without committing the configuration changes.
• Cancel - Remains in the configuration mode, without committing the configuration changes.
