HI experts

There is a problem of cedge vrrp,the configuration as below.

Master device:
Current configuration : 255 bytes
!
interface GigabitEthernet4.101
 encapsulation dot1Q 101
 vrf forwarding 1
 ip address 172.16.101.252 255.255.255.0
 ip mtu 1496
 vrrp 1 address-family ipv4
  timers advertise 100
  priority 110
  vrrpv2
  address 172.16.101.254 primary
  exit-vrrp
end

Backup Device:
Current configuration : 240 bytes
!
interface GigabitEthernet4.101
 encapsulation dot1Q 101
 vrf forwarding 1
 ip address 172.16.101.253 255.255.255.0
 ip mtu 1496
 vrrp 1 address-family ipv4
  timers advertise 100
  vrrpv2
  address 172.16.101.254 primary
  exit-vrrp
end

I can see there are lots of logging about vrrp switchover;

I also try to issue debug command to check it, but the error log that i feel strange. Could you help me to analysis this issue ? many thanks.
