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.
