What is the least intrusive method to manually flip VRRP mastership

‎08-30-2019 02:37 AM

Hi all,

With a redundant MX480 setup, can I ask the simplist way to transfer vrrp 'master' for fifty L3 interfaces, other than reboot or switching redundant RE roles?.

Thank you

Hi,

You can change the priority on back-up to higher. By default, a higher-priority backup router preempts a lower-priority master router and mastership will switch.

Hi Anawaz,

I hope you are aware of VRRP priority and preemption concept.  Please review following document:

 

        https://www.juniper.net/documentation/en_US/junos/topics/task/configuration/vrrp-preemption-configur...

If you can share your current configuration that will help to answer more precisely.

However, if you want to just manually flip the mastership without causing a major impact and configuration change. You can shut down the ethernet interface on VRRP master.


Please mark my response as solution if it asnwers your query, kudos are appreciated too!

Thanks

Agreed with this solution and to make things simple i'd opt to replace pattern given the number of interfaces.

thank you!

 You can change the VRRP priority of the set of interfaces using groups and apply the group to the interface hierarchial knob.
