How do I navigate to a sibling route?

Question

Let\'s presume I got this router config

export const EmployeeRoutes = [
   { path: \'sales\', component: SalesComponent },
   { path: \'contacts\', component

The RouterLink directive always treats the provided link as a delta to the current URL:

[routerLink]="['/absolute']"
[routerLink]="['../../parent']"
[routerLink]="['../sibling']"
[routerLink]="['./child']"     // or
[routerLink]="['child']" 

// with route param     ../sibling;abc=xyz
[routerLink]="['../sibling', {abc: 'xyz'}]"
// with query param and fragment   ../sibling?p1=value1&p2=v2#frag
[routerLink]="['../sibling']" [queryParams]="{p1: 'value', p2: 'v2'}" fragment="frag"

The navigate() method requires a starting point (i.e., the relativeTo parameter). If none is provided, the navigation is absolute:

constructor(private router: Router, private route: ActivatedRoute) {}

this.router.navigate(["/absolute/path"]);
this.router.navigate(["../../parent"], {relativeTo: this.route});
this.router.navigate(["../sibling"],   {relativeTo: this.route});
this.router.navigate(["./child"],      {relativeTo: this.route}); // or
this.router.navigate(["child"],        {relativeTo: this.route});

// with route param     ../sibling;abc=xyz
this.router.navigate(["../sibling", {abc: 'xyz'}], {relativeTo: this.route});
// with query param and fragment   ../sibling?p1=value1&p2=v2#frag
this.router.navigate(["../sibling"], {relativeTo: this.route, 
    queryParams: {p1: 'value', p2: 'v2'}, fragment: 'frag'});

// RC.5+: navigate without updating the URL 
this.router.navigate(["../sibling"], {relativeTo: this.route, skipLocationChange: true});
