angular - routerlink not working in angular2

Question

I have checked all the tutorial and didn't find, what i am doing wrong.

AppModule :

 import { BrowserModule } from '@angular/platform-browser';
 import { NgModule } from '@angular/core';
 import { FormsModule } from '@angular/forms';
 import { HttpModule } from '@angular/http';

 import { AppComponent } from './app.component';
 import {BlogComponent} from './blog/blog.component';
 import { PortfolioComponent } from './portfolio/portfolio.component';
 import { NavbarComponent } from './shared/navbar/navbar.component';
 import {TimelineComponent} from './timeline/timeline.component';
 import {HomeComponent} from './home/home.component';

 import { routing} from './app.routing';

 @NgModule({
   declarations: [
     AppComponent,
     PortfolioComponent,
     NavbarComponent,
     BlogComponent,
     TimelineComponent,
     HomeComponent
   ],
   imports: [
     BrowserModule,
     FormsModule,
     HttpModule,
     routing
   ],
   providers: [],
   bootstrap: [
     AppComponent
   ]
 })
 export class AppModule { }
 </i>

 Navigation Bar 
 <i>
 <div id="navbar" class="collapse navbar-collapse">
       <ul class="nav navbar-nav">
         <li><a routerlink="/portfolio">Portfolio</a></li>
         <li><a routerlink="/timeline">Timeline</a></li>
         <li><a routerlink="/blog">Blog</a></li>
       </ul>
       <ul class="nav navbar-nav navbar-right">
         <li><a href="#contact">Professionals</a></li>
         <li><a href="#contact">Students</a></li>
       </ul>
     </div>
 </i>

 NGModule :
 <i>
 import { BrowserModule } from '@angular/platform-browser';
 import { NgModule } from '@angular/core';
 import { FormsModule } from '@angular/forms';
 i

 import { routing} from './app.routing';

 @NgModule({

   imports: [
     BrowserModule,
     FormsModule,
     HttpModule,
     routing
   ],
   providers: [],
   bootstrap: [
     AppComponent
   ]
 })

Answer 1

Not sure the code you pasted is ordered correctly but I can see 2 mistakes.

First, you're setting the routerlink attribute instead of routerLink, notice it's case sensitive.

Second, I'm pretty sure you don't import RouterModule in the module with the relevant component, make sure you do that so you get access to the routerLink directive in the first place.
