Can Back up RE in Virtual Chassis be preempted by new higher priority switch ?

‎12-23-2018 09:07 AM

Hi everyone,

 

I did find Juniper doc describing how MASTER SW is elected in VC, however I do not see how the Virtual Chassis behave in following situation:

Existing Virtual Chassis  state( using dynamic method i.e no non-provisioned method):

 

SW1 MASTE RE Priority 140

SW2 BACK UP RE priority 130

New  SW 3 with priority 131 is connected to VC, will SW3 become new BACK UP RE and SW2 is demoted to line card role?

 

Thanks and have a nice weekend!!

In this case it should happen only if you reboot SW2.

It happens because changing role between RE and line card causes some interruptions in service.

Please use check these two links: 1 and 2.
