Links Visible To Vendors Only

I have a footer menu block called "Support". It is HTML with Smarty Support. Some of the links are for vendor only. What code can I use to specify links that are only for vendors to see? Something like...

{if user is vendor}
vendor links
{else}
other links
{/if}

Please try

{if $auth.user_type == 'V'}
     vendor links
{else}
     other links
{/if}
