redirect something_test to something

Just wondering is there a way to have it so that

http://mysite/contactus can also go http://mysite/contact I do not mind entering in the list of thing i think would be useful, can anyone help?

e.g.
http://mysite/home to http://mysite/index
http://mysite/contact to http://mysite/contact
http://mysite/jobs to http://mysite/contact
http://mysite/map to http://mysite/contact
etc….

Thanks
