Auto-stitching a brownfield service

Auto-stitching

By default, automatic stitching of services is disabled in IBSF. Users can either stitch a service type manually by following the above procedure or enable auto-stitching in which each service type will have a predefined list of supported stitching algorithms that can be selected to run automatically.

The auto-stitching is supported for service-types Eline, Elan, IES, and L3 VPN for the algorithms mentioned in the table below:

Service Type	Algorithm
Eline	vcid, evi, route-target, local and service-name
Elan	vcid, evi, route-target and service-name
IES	service-name
L3 VPN	route-target and service-name

The auto-stitching is disabled by default. The user has to enable the auto-stitching per service-type and specific algorithm type.

The different API calls for auto-stitching are mentioned below.
