We add a new irb 3 in the same VRRP group ID 10 with an existing irb 6.
The VRRP group ID (10) had problems passing traffic intermittently on the new irb 3 IRB interface.
Track route State Cost Interface Group Cfg Run VR State
0.0.0.0/0 up 50 irb.6 10 100 100 master
0.0.0.0/0 up 50 irb.3 10 100 100 master
The devices behind irb 3 were not responding over the network. When irb 3 is bounced (disable/delete disable) normal communications was restored.
Our suggestion is to configure only 1 interface to each VRRP group because of the functionality of the VRRP, If on a device we have 2 interfaces configured in the same VRRP group and one device goes down, both interfaces go down and the failover is wrongly done to the other device.
