making a first determination, based on a matching of at least one data field of the set of data fields with the redirect criteria, to steer the MAC frame towards a common virtual VTEP Internet Protocol (IP) address instead of a destination IP address specified in the MAC frame, wherein the destination IP address is associated with a first destination host; and
transmitting, based on the first determination, the MAC frame towards a service device operatively connected to the common virtual VTEP IP address.
