I have a site that has three sitemap files to cover the entire site.

http://www.example.com/sitemap.xml
http://www.example.com/sitemap1.xml
http://www.example.com/sitemap2.xml

Is it best to just add the first one to my robots.txt or all three:

sitemap: http://www.example.com/sitemap.xml
sitemap: http://www.example.com/sitemap1.xml
sitemap: http://www.example.com/sitemap2.xml
