Abstract
A first leaf switch may receive from a first host, a request for a second host that is not known at the first leaf switch. The first host may be within a first End Point Group (EPG) and the second host being within a second EPG. The first EPG and the second EPG may be in a Bridge Domain (BD). Flood in encapsulation may be enabled for the first EPG and for the second EPG. Next, the first leaf switch may flood the request locally in the first EPG and to a spine switch with a VNID of the first EPG. The spine switch may then flood the request to a second leaf switch where the BD is present. The second leaf switch may send a glean request for the second host, receive, in response to sending the glean request, a reply, and learn the second host locally in response to receiving the reply.
