This article describes the issue of the VRRP PDU interface’s statistics advertisement not always correctly populating the count.
The VRRP PDU statistics, which displays the interface’s advertisement for sent and/or received, is displaying the count as 0 or in certain cases, it will display a negative count.
This issue is due to a software bug or in certain cases, the sent or received advertisement is displaying the value as 0 due to the VRRP hanging.
In this instance, on the MX80 device, there are no sent or received Advertisements. This is a known issue on all MX80 series routers.

In this instance, VRRP was set up on the 1 and 2 MX routers. Router 2 was a failover router that does not populate the received advertisements. The switch, which is sending the advertisement, verified that router 2 was suppose to be receiving these advertisements. Restarting VRRP via the restart vrrp command resolved the issue.
