Cisco ASR 9000 Series Configuration Guidelines

4. ethernet-segment
5. mac-flush mvrp
6. timers [flushagain | recovery]
7. Use the commit or end command.
DETAILED STEPS
Step 1 configure
Example:
RP/0/RSP0/CPU0:router# configure
Enters the Global Configuration mode.
Step 2 evpn
Example:
RP/0/RSP0/CPU0:router(config)# evpn
Enters EVPN configuration mode.
Step 3 interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config-evpn)# interface gigabitEthernet 0/1/0/4
Enters the physical port interface or the bundle interface configuration mode.
Step 4 ethernet-segment
Example:
RP/0/RSP0/CPU0:router(config-evpn-ac)# ethernet-segment
Enters the EVPN ethernet-segment configuration mode.
Step 5 mac-flush mvrp
Example:
RP/0/RSP0/CPU0:router(config-evpn-ac)#
Specifies MAC flush mode for this Ethernet Segment.
Step 6 timers [flushagain | recovery]
Example:
RP/0/RSP0/CPU0:router(config-evpn-ac)# timers flushagain 40
Configures per Ethernet segment 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.
