Your common child modal component will be as below

import {Component,Input, ViewChild} from '@angular/core';
import { ModalDirective } from 'ng2-bootstrap/ng2-bootstrap';

@Component({
  selector: 'common-modal',
  template: `
   <div bsModal #childModal="bs-modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-sm">
    <div class="modal-content">
      <div class="modal-header">
        <h4 class="modal-title pull-left">{{title}}</h4>
        <button type="button" class="close pull-right" aria-label="Close" (click)="hideChildModal()">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        <ng-content select=".modal-body"> </ng-content>
      </div>

      <div class="modal-footer">
        <div class="pull-left">
          <button class="btn btn-default" (click)="hide()"> Cancel </button>
        </div>
      </div>
    </div>
  </div>
</div>
  `,
})
export class CommonModalComponent {
   @ViewChild('childModal') public childModal:ModalDirective;
   @Input() title:string;
  constructor() {
  }
  show(){
    this.childModal.show();
  }
  hide(){
    this.childModal.hide();
  }
}

Using the child component in your parent component will look as below

import {Component, ViewChild, NgModule,ViewContainerRef} from '@angular/core'
import { BrowserModule } from '@angular/platform-browser';
import { ModalDirective,ModalModule } from 'ng2-bootstrap/ng2-bootstrap';
import {CommonModalComponent} from './child.modal';
@Component({
  selector: 'my-app',
  template: `
    <button type="button" class="btn btn-primary" (click)="childModal.show()">Open modal</button>
    <common-modal  #childModal [title]="'common modal'"> 
    <div class="modal-body">
    Hi heloo </div>
    </common-modal> 

  `,
})
export class AppComponent {
  @ViewChild('childModal') childModal :CommonModalComponent;
  constructor(private viewContainerRef: ViewContainerRef) {
  }

}

Using the above code you can have a separate common modal dialog which can be reused, so that your header & footer remains the same and you can use Content-Projection to use change the body of the modal dialog.
