Narrative:
Received a TCASII RA while conducting an ILS approach to runway 25R at lax. This was caused by a commuter aircraft that was being vectored by approach control from the south or southeast for an apparent visual approach to runway 25L. The RA was received when the other aircraft was approximately 2-3 mi distance according to TCASII.
