Dear expert,
Previously i have condition where VRRP have master-master state.
Node A :
SR_A_us(En) 0107 255 10.168.49.209 MSTR 00:00:5e:00:01:6b 0 0 0 Y 0.10
SR_A_us(En) 0108 100 10.168.49.210 BKUP 00:00:5e:00:01:6c 0 0 0 Y 0.10
Node B :
SR_A_us(En) 0107 100 10.168.49.209 MSTR 00:00:5e:00:01:6b 0 0 0 Y 0.10
SR_A_us(En) 0108 255 10.168.49.210 MSTR 00:00:5e:00:01:6c 0 0 0 Y 0.10
currently the switch is running on 16.1.
And i'm aware there a patch for dual master vrrp state delivered on 16.2.3.5
what could the impact on traffic during above condition? when we still have one vrid in master-master state and the other one in normal condition (master-backup).

Hi Puji,
It can cause MAC moves for the VRRP MAC in downstream switches causing potential routing issues/drops/latency, etc.

Hi Puji,
Since in this state, both VRRP Masters own the VRRP MAC, potentially, any sort of traffic can be affected since the VRRP MAC can flap between two ports connected to the two VRRP masters. If the traffic is to be routed by the VRRP masters, it can be affected.

Hi Sushruth,
txs a lot for replying.
yup, i just check there're many RTP packet lost during vrrp master-master state.
