Symptom
Ping fail
Please note that this ping failure is observed only for the first VRRPv2 group configured on the device. The ping to a secondary VIP if configured is also successful. Subsequent VRRPv2 groups configured do not face this issue. When more than one VRRPv2 groups are configured, responses to ARP requests are not sent for the first group.
Conditions
- First VRRPv2 group configured on the device.
- ONLY in release 17.6.4
- applicable to all IOS XE platforms, virtual devices only.
Workaround
Since this issue is observed only for the first VRRPv2 group configured on the device, a temporary workaround would be to first configure a dummy VRRP group, since the subsequent groups configured will not be affected by the ping failure issue.
Another workaround is to use VRRPv3 since only the VRRPv2 VIP is affected.
Further Problem Description
interface VlanX
ip address x.x.x.1 255.255.255.0
vrrp 1 ip x.x.x.254
ping result:
Router#ping x.x.x.1 >>>>>>> ping successful to VlanX address .
!!!!!
Router#ping x.x.x.254 >>>>>>> ping fail to vrrp Virtual ip addess

Please note, if the backup device is unable to ping the VIP, this causes reachability issues for all other hosts as well.
