Presented herein are techniques through which a list of functions (FUNC) that are to be invoked in a system may be carried as part of a Segment Routing for Internet Protocol version 6 (SRv6) micro-Segment Identifier (uSID) or a bitmask in an interesting packet. A first packet may be used to invoke the functions and, once invoked, a more specific entry for the address can be instantiated in a forwarding table so as to avoid attempting to invoke the same functions for subsequent packets.
