Abstract: In some examples, a computing device comprises a first service function instance to apply a service function and a service function forwarder to: receive a first layer 3 routing protocol route advertisement that includes service function instance data for a second service function instance, the service function instance data indicating a service function type and a service identifier for the service function instance; receive a second layer 3 routing protocol route advertisement that includes service function chain data for a service function chain, the service function chain data indicating a service path identifier and one or more service function items; and send, to the second service function instance and based at least on determining a service function item of the one or more service function items indicates the second service function instance, a packet classified to the service function chain.
