Some traffic denied on firewall when EIGRP flaps

I'm working on a  hub and spoke enviroment, for the spoke ( remote sites ) we have 2 routers running HSRP. I notice when EIGRP flaps on the primary router at the spoke I will see a bunch of denies on the firewall at the hub. Is this expected behavior due to brief moment of asymmetric routing when EIGRP flaps?

Hi, What kind of blocks you

Hi,

 

What kind of blocks you are seeing in firewall? Because if the eigrp flaps then definitely there would be a minimal routing issue, for which traffic might not go through or return respone would not be coming from the actual responder..... there might be a deny due to inspect failure or something like this...

 

Can you paste the deny logs that you observe during eigrp flaps?

 

Regards

Karthik
