How to work with multiple configuration files per microservice? about ocelot

[raman-m]

Sachin, fork Ocelot repo first to look into the Ocelot code!

After forking Ocelot you will figure out that AddJsonFile method is a part of JsonConfigurationExtensions class from Microsoft.Extensions.Configuration namespace!
If you press F12 key multiple times, you will get to this Microsoft ASP.NET implementation:

        /// <summary>
        /// Adds a JSON configuration source to <paramref name="builder"/>.
        /// </summary>
        /// <param name="builder">The <see cref="IConfigurationBuilder"/> to add to.</param>
        /// <param name="provider">The <see cref="IFileProvider"/> to use to access the file.</param>
        /// <param name="path">Path relative to the base path stored in
        /// <see cref="IConfigurationBuilder.Properties"/> of <paramref name="builder"/>.</param>
        /// <param name="optional">Whether the file is optional.</param>
        /// <param name="reloadOnChange">Whether the configuration should be reloaded if the file changes.</param>
        /// <returns>The <see cref="IConfigurationBuilder"/>.</returns>
        public static IConfigurationBuilder AddJsonFile(this IConfigurationBuilder builder, IFileProvider? provider, string path, bool optional, bool reloadOnChange)
        {
            ThrowHelper.ThrowIfNull(builder);

            if (string.IsNullOrEmpty(path))
            {
                throw new ArgumentException(SR.Error_InvalidFilePath, nameof(path));
            }

            return builder.AddJsonFile(s =>
            {
                s.FileProvider = provider;
                s.Path = path;
                s.Optional = optional;
                s.ReloadOnChange = reloadOnChange;
                s.ResolveFileProvider();
            });
        }

I have no idea how inner MS implementation merges config JSON.

If you call

                    .AddJsonFile("student.ocelot.Development.json", false, true)
                    .AddJsonFile("teacher.ocelot.Development.json", false, true)

and they describe the same routes, seems the second file will overwrite the routes from the first one.
Microsoft classes don't merge!
