you can use child e.g.

const appRoutes: Routes = [
    { path: '', component: MainComponent,

            { path: 'home'  component:HomeComponent},
            { path: 'about', component: AboutComponent},
            { path: 'contact', component: ContactComponent},
               ..others that share the same footer and header...

        }
    },
    { path: 'login', component: LoginComponent },
    { path: 'register', component: RegisterComponent },
    { path: 'admin', component:AdminComponent, 
         children{
            { path: 'dashboard', component: DashboardComponent },
            { path: 'profile', component: ProfileComponent }
               ..others that share the same footer and header...
         }
    }
    { path: '**', redirectTo: '' }
];
