The local HMM host database is populated with host MAC/IP binding under the partition VRF.  A DFA administrator can 
review the summary of host counts and detailed output listing learned hosts’ information. The new host entry, com-
prised of IP and MAC pair, will be learned against a specific edge interface for an Anycast SVI previously applied by 
auto-config profile instantiation.

Locally, the leaf switch RIB is updated with the /32 route learned by HMM. In this way HMM is a client protocol of the 
Routing Information Base in NX-OS, just as ARP, OSPF, EIGRP, or any other routing protocol would be.
