Coding the path in the NCP

In the NCP generation, find the path for destination subarea 310:

         PATH DESTSA=310,
               ER0=(2,1),ER1=(71,80),
               ER3=(2,1),ER4=(3,80),ER5=(310,80),
               ER6=(310,80),ER7=(310,1),ER8=(71,80),
               ER9=(2,1),ER10=(1,1),ER11=(400,80),
               ER12=(1,1),
               VR0=6,
               VRPWS00=(1,3),VRPWS01=(1,3),VRPWS02=(1,3),
               VR1=9,
               VRPWS10=(2,6),VRPWS11=(2,6),VRPWS12=(2,6),
               VR2=3,
               VRPWS20=(2,6),VRPWS21=(2,6),VRPWS22=(2,6),
               VR3=8,
               VRPWS30=(2,6),VRPWS31=(2,6),VRPWS32=(2,6),
               VR4=4,
               VRPWS40=(2,6),VRPWS41=(2,6),VRPWS42=(2,6),
               VR5=11,
               VRPWS50=(2,6),VRPWS51=(2,6),VRPWS52=(2,6),
               VR6=10,
               VRPWS60=(3,9),VRPWS61=(3,9),VRPWS62=(3,9),
               VR7=7,
               VRPWS70=(3,9),VRPWS71=(3,9),VRPWS72=(3,9)

Change the definition for ER2 to destination subarea 310 and TGN1 and map VR1 to ER2:

         PATH DESTSA=310,
               ER0=(2,1),ER1=(71,80),ER2=(310,1),
               ER3=(2,1),ER4=(3,80),ER5=(310,80),
               ER6=(310,80),ER7=(310,1),ER8=(71,80),
               ER9=(2,1),ER10=(1,1),ER11=(400,80),
               ER12=(1,1),
               VR0=6,
               VRPWS00=(1,3),VRPWS01=(1,3),VRPWS02=(1,3),
               VR1=2
               VRPWS10=(2,6),VRPWS11=(2,6),VRPWS12=(2,6),
               VR2=3,
               VRPWS20=(2,6),VRPWS21=(2,6),VRPWS22=(2,6),
               VR3=8,
               VRPWS30=(2,6),VRPWS31=(2,6),VRPWS32=(2,6),
               VR4=4,
               VRPWS40=(2,6),VRPWS41=(2,6),VRPWS42=(2,6),
               VR5=11,
               VRPWS50=(2,6),VRPWS51=(2,6),VRPWS52=(2,6),
               VR6=10,
               VRPWS60=(3,9),VRPWS61=(3,9),VRPWS62=(3,9),
               VR7=7,
               VRPWS70=(3,9),VRPWS71=(3,9),VRPWS72=(3,9)

Attention: Whenever you change paths, make sure that you are not deleting a path that you need for another route.
