What’s Changed in Release 21.2R2

Learn about what changed in this release for ACX Series routers.

EVPN

  • Minimum auto-recovery time reduced for duplicate MAC address detection (ACX Series, PTX Series and QFX Series)—Junos OS has changed the minimum value allowed for auto-recovery time for duplicate MAC address detection from 5 minutes to 1 minute. The auto-recovery time is the length of time that the device suppresses a duplicate MAC address. Reducing the auto-recovery time allows customers to quickly recover from a MAC address duplication state. You configure the auto-recovery-time option under the duplicate-mac-detection statement at the edit routing-instances routing-instance-name protocols evpn or edit protocols evpn hierarchy.
