! This script sets up a DECNIS with 3 circuits as an IP multicast
! router.
!
! This script is divided into three sections:
!	EXTRA_CREATE.NCL
!	EXTRA_SET.NCL
!	EXTRA_ENABLE.NCL
! Each section should be added to the relevant user NCL script file for your
! DECNIS. 
! For more information about the user NCL script files, refer to 
! the DECNIS Management manual.
