  • 1.  Why JunosA is Master with lower priority in vrrp?

    Hi, Two router MX960 are configured as below. My question is why JunosA is Master, while JunosB is backup when the command "show vrrp brief". Thank you

     

    JunosA>show configuration | display set | match "unit 2"

    set interfaces irb unit 2 enable
    set interfaces irb unit 2 family inet address 10.7.1.3/26 vrrp-group 1 virtual-address 10.7.1.1
    set interfaces irb unit 2 family inet address 10.7.1.3/26 vrrp-group 1 priority 105
    set interfaces irb unit 2 family inet address 10.7.1.3/26 vrrp-group 1 no-preempt
    set interfaces irb unit 2 family inet address 10.7.1.3/26 vrrp-group 1 accept-data

     

    JunosB>show configuration | display set | match "unit 2"

    set interfaces irb unit 2 enable
    set interfaces irb unit 2 family inet address 10.7.1.2/26 vrrp-group 1 virtual-address 10.7.1.1
    set interfaces irb unit 2 family inet address 10.7.1.2/26 vrrp-group 1 priority 110
    set interfaces irb unit 2 family inet address 10.7.1.2/26 vrrp-group 1 no-preempt
    set interfaces irb unit 2 family inet address 10.7.1.2/26 vrrp-group 1 accept-data

    HI !

     

    because the master was here first and you configured "no-preempt" which means whoever is the master will not switch over as long as he is active

     

    regards

    Thank you so much. I think you are right though I have not tested it yet. I know cisco has this same issue.
