Ivie's funeral at the Church of Jesus Christ of Latter-day Saints meetinghouse begins at 10 a.m.
The service will be broadcast in several Mormon meeting houses across southern Arizona.
Ivie is survived by his wife, two young daughters, parents and siblings.
Ivie was shot to death early Tuesday near the Mexican border as three agents responded to an alarm that was triggered by a sensor aimed at detecting smugglers. A second agent was wounded.
The FBI says it appears the agents opened fire on each other in a case of friendly fire.
A second funeral will be held Thursday morning at Utah Valley University in Orem, Utah.
