VRRP logging discrepancy

On one of two VRRP devices we saw:

 

SSH@DEFSD-RTR-01#sh log | inc VRRP
Aug 1 11:15:10:N:VRRP: VRRPE intf state changed, intf v125, vrid 1, state backup
Aug 1 11:15:09:N:VRRP: VRRPE intf state changed, intf v125, vrid 1, state master
Aug 1 11:13:16:N:VRRP: VRRPE intf state changed, intf v57, vrid 1, state backup
Aug 1 11:13:13:N:VRRP: VRRPE intf state changed, intf v57, vrid 1, state master
Aug 1 11:13:11:N:VRRP: VRRPE intf state changed, intf v56, vrid 1, state backup
Aug 1 11:13:10:N:VRRP: VRRPE intf state changed, intf v55, vrid 1, state backup
Aug 1 11:13:10:N:VRRP: VRRPE intf state changed, intf v55, vrid 1, state master
Aug 1 11:13:10:N:VRRP: VRRPE intf state changed, intf v56, vrid 1, state master

During the same time roughly on the other VRRP devicde  we see:

 

Aug 1 11:17:38:W:IP: IP: Duplicate IP address 10.49.25.6 detected sent from MAC address 02e0.52a8.0f01 interface 7/2, 1 packets
Aug 1 11:17:38:W:IP: IP: Duplicate IP address 10.55.5.129 detected sent from MAC address 02e0.52d5.dc01 interface 7/2, 1 packets
Aug 1 11:17:38:W:IP: IP: Duplicate IP address 10.55.5.6 detected sent from MAC address 02e0.52c4.1501 interface 7/2, 1 packets
Aug 1 11:15:09:W:IP: IP: Duplicate IP address 10.49.25.6 detected sent from MAC address 02e0.52a8.0f01 interface 7/2, 1 packets
Aug 1 11:13:13:W:IP: IP: Duplicate IP address 10.55.5.129 detected sent from MAC address 02e0.52d5.dc01 interface 7/2, 1 packets
Aug 1 11:13:10:W:IP: IP: Duplicate IP address 10.55.0.6 detected sent from MAC address 02e0.520b.1501 interface 7/2, 1 packets
Aug 1 11:13:10:W:IP: IP: Duplicate IP address 10.55.5.6 detected sent from MAC address 02e0.52c4.1501 interface 7/2, 1 packets

 

I do understand that  the duplicate IP addesss is a by product of FHRP.

 

Logging is setup the same on both routers.

 

What I dont understand is why only one router is logging a VRRP state change and the other one is not.  L

Re: VRRP logging discrepancy

From what I have read, the Master logs the changes.
