Abstract
Example methods and computer systems for packet handling for active-active stateful service insertion are disclosed. One example may involve a computer system detecting a packet addressed from a source address to a service endpoint address. Based on configuration information associated with the service endpoint address, the computer system may identify a first active logical service router (SR) and a second active logical SR that are both associated with the service endpoint address and configured to operate in an active-active mode. The first active logical SR may be selected over the second active logical SR by mapping tuple information to the first active logical SR. The computer system may generate an encapsulated packet by encapsulating the packet with an outer header addressed to an outer destination address associated with the first active logical SR and send the encapsulated packet towards the first active logical SR for processing according to a stateful service.
