The REGISTER request contains the "pre-loaded route set". Pre-loaded route sets are for security reasons disabled in the default config (to-tag check):

if (has_totag()) {
   # sequential request withing a dialog should
   # take the path determined by record-routing
   if (loose_route()) {
      ...
      route(RELAY);
   } else {
   ...

Either remove the totag check or add an explicit entry (eg. before the above block):

if (is_method("REGISTER") {
   # allow pre-loaded route set for REGISTER
   if (loose_route()) {
      ...
      route(RELAY);
   }
}

Hello all,

I am having little trouble routing registrations based on route header
in following configuration. UA sends registration to P1 and P1 is
ignoring “route header” and forwards registration request to Registrar.

I am using default kamailio configuration. Is there any thing I need to
add to default config to enable route headers?
