Thank you for providing the additional information. It does show that HSRP does appear to be running correctly and that router 1 is the active router for HSRP. So I started thinking about why would the core send traffic to router 2 if router 1 is the active router. If the core were forwarding to the HSRP virtual address then it should have gone to router 1. Then I realize that you are running OSPF between these routers. OSPF forms its adjacency using the interface address not the virtual address. So if the core is forwarding traffic using OSPF learned routes then it would not be using the HSRP virtual address but would use the interface address and that may be why it was sending traffic to router 2.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
