Hello

I have never performed any FHRP on nexus so my commnets would be associated with troubleshooting IOS FRHP.'s


1) are the peers using the same version
2) Is authentication applkied and is this correct
3) Acls' not blocking HRSP Hellos - 
4) Layer1/2 connectivity ( vtp/stp etc.)
5) can you ping between the peers
6) ip rediracts enabled (  by default its disabled when hrsp is enabled)

Show Standby - cross check configuration

Hello,

Just few clarification based on the output provied, Is both the switches are in normal trunk between the sites and you are running HSRP between the sites.

As per out shown for show hsrp vlan 3 that clearly shows active router and standby router without any issue.

Could you pos the HSRP configiration of the vlan 3 from both the switches as well.
