mod_rewrite redirects only index page

mod_rewrite redirects only index page

The problem is that following .htaccess syntax:
Options +FollowSymLinks
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} robots.txt$ [NC]
RewriteRule ^([^/]+) $1 [L]
RewriteCond %{HTTP_HOST} ^bd-spb\.ru$ [NC]
RewriteRule ^(.*)$ http://xn----8sbbkdenhe5aqs7a.xn--p1ai/$1 [R=301,L]
RewriteCond %{HTTP_HOST} ^www.bd-spb\.ru$ [NC]
RewriteRule ^(.*)$ http://xn----8sbbkdenhe5aqs7a.xn--p1ai/$1 [R=301,L]
Redirects only index page. So if I go to bd-spb.ru I will get
áèçíåñ-äèàëîã.ðô, but if I go for example here its not redirects me here.
How to make this happens?
