ECMP Support in Service Chain

Equal-cost multipath (ECMP) can be used to distribute traffic across VMs.

Service Chain with Equal-Cost Multipath in Active-Active Mode

To support ECMP in the service chain, create multiple port tuples within the same service instance. The labels should be the same for the VM ports in each port tuple. For example, if port tuple 1 uses the labels left and right, then port tuple 2 in the same service instance should also use the labels left and right for its ports.

When there are multiple port tuples, the default mode of operation is active-active.

Service Chain with Health Check

Service chain Version 2 also allows service instance health check configuration on a per interface label. This is used to monitor the health of the service.
