BuddyPress.org

I have Multisite with Buddypress on Subsite.
I want to link author profile from all sites to buddypress author profile on subsite.
I tried to use this https://gist.github.com/dcavins/94e4989cad997d0553e8e5db37f30b40

add_filter( ‘author_link’, ‘dc_bp_filter_author_link’, 10, 2 );
function dc_bp_filter_author_link( $link, $author_id ) {
return bp_core_get_user_domain( $author_id );
}

BUT this needs to have buddypress active on all sites.
