If you are looking for piping within same server then it is really simple as mentioned here in docs:

If you are looking for piping between servers then going through this source code file of mediasoup will help, you can see how they create the piping between routers:

github.com

versatica/mediasoup/blob/v3/node/src/Router.ts

import { v4 as uuidv4 } from 'uuid';
import { Logger } from './Logger';
import { EnhancedEventEmitter } from './EnhancedEventEmitter';
import * as ortc from './ortc';
import { InvalidStateError } from './errors';
import { Channel } from './Channel';
import { PayloadChannel } from './PayloadChannel';
import { Transport, TransportListenIp } from './Transport';
import { WebRtcTransport, WebRtcTransportOptions } from './WebRtcTransport';
import { PlainTransport, PlainTransportOptions } from './PlainTransport';
import { PipeTransport, PipeTransportOptions } from './PipeTransport';
import { DirectTransport, DirectTransportOptions } from './DirectTransport';
import { Producer } from './Producer';
import { Consumer } from './Consumer';
import { DataProducer } from './DataProducer';
import { DataConsumer } from './DataConsumer';
import { RtpObserver } from './RtpObserver';
import { ActiveSpeakerObserver, ActiveSpeakerObserverOptions } from './ActiveSpeakerObserver';
import { AudioLevelObserver, AudioLevelObserverOptions } from './AudioLevelObserver';
import { RtpCapabilities, RtpCodecCapability } from './RtpParameters';

And if you want me to simplify it then here it is:
We have two servers server 1, server 2. Producer 1 is on server 1 and we want this producer to be piped on server 2 so here are the steps:

Create pipetransport on server 1, lets call is pipetransport 1
Create pipetransport on server 2, lets call is pipetransport 2
Exchange connect parameters of pipetransport 1, pipetransport 2 with eachother. Now they are connected
Consume producer 1 on pipetransport 1 (from server 1), now pipetransport 1 is ready to give producer 1 to pipetransport 2
Produce producer 1 on pipetransport 2, with the help of producer parameters from previous step, now pipetransport 2 have producer 1 and so does server 2
Consume producer 1 from server 2 just like normal.
