1. A method comprising:
receiving, by a computing device, a request packet from a workload at a first logical interface of a logical router;
determining, by the computing device, that a source address of the request packet is a first link local address for the workload and a destination address of the request packet is a second link local address for the first logical interface of the logical router, wherein a second logical interface of the logical router includes the second link local address;
storing, by the computing device, an identifier for the first logical interface as an egress interface, the identifier distinguishing the first logical interface from the second logical interface;
performing, by the computing device, a service for the request packet and generating a response packet based on the service, the response packet including the source address of the second link local address for the first logical interface of the logical router and the destination address of the first link local address for the workload; and
using, by the computing device, the identifier to select the first logical interface as the egress interface to send the response packet.
