Claim 7:
8. A non-transitory computer-readable storage medium containing instructions, that when executed, control a computer system to be operable for:
configuring, at a first host, an overlay channel for sending packets to check whether a failure has occurred at an active edge services gateway workload on a second host, wherein the first host and a second host are connected via a layer 3 network;
generating, at a standby edge services gateway workload on the first host, a packet to check whether the failure has occurred at the active edge services gateway workload on the second host;
encapsulating the packet; and
sending, from the standby edge services gateway workload on the first host, the encapsulated packet to the active edge services gateway workload on the second host using the overlay channel via the layer 3 network, wherein the packet is decapsulated and forwarded to the active edge services gateway workload at the second host.
