Embed vimeo video into the body field
The input formats can be configured at /admin/settings/filters/list so that you can add the &lt;iframe&gt; tag as an allowed tag to the input format that you are using.

Though, I think for security purposes, you may want to allow tags other than &lt;iframe&gt;.  One option it so use Vimeo's 'old' embed code (the link would be just above the box where you copy the code from).  The old embed code uses the &lt;embed&gt; and &lt;object&gt; tags, which you'll likely still have to add to the filter's allowed HTML tag list.
