Hi David, The support for HSRP is mainly due to queuing not supported on FEX host interfaces prior to 6.2.2 For Cisco NX-OS Release 6.2(2) and later releases,the Cisco Fabric Extenders support Layer 3 protocol adjacencies onhostinterfaces (HIFs)and DSCP to queue mapping. Before CiscoNX-OS Release 6.2(2),you can configure a Fabric Extender (FEX) port as a Layer 3 interface for host connectivity, but not for routing.   https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/nx-os/interfaces/configuration/guide/b-Cisco-Nexus-7000-Series-NX-OS-Interfaces-Configuration-Guide-Book/configuring-layer-3-interfaces.pdf   FEX supports Layer-3 sub-interface   https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus2000/sw/configuration/guide/rel_521/b_Configuring_the_Cisco_Nexus_2000_Series_Fabric_Extender_rel_5_2/b_Configuring_the_Cisco_Nexus_2000_Series_Fabric_Extender_rel_5_2_chapter_01.html#d25e332a1635   ...

Curios to know what happens if you reboot Leaf-4 ... View more

I do not think there is a problem in your design and test scenario. If the leaf-4 gets disconnected from the Fabric the traffic has to go from Leaf-4 to Leaf-3 over peer-link and from Leaf-3 it should be forwarded. vPC loop avoidance feature will only kick in if the traffic gets forwarded over the peer-link and have to traverse another vPC. In this case the traffic gets forwarded from Leaf-4 to Leaf-3 and it has to be forwarded from Leaf-3 to Spine via a Layer-3 interface So something might not have set correctly in configuration or you might be hitting some bug ...
