Steps for displaying routes

You can display the routes between the subareas in your routes to identify the problem area.

Note: Displays shown are abbreviated. If you run this display on your system, it will list information for all explicit routes from 0 to 15.

Display the route from Host15 to Host500 with A04NCP as the destination subarea. From Host15, issue the following command:

  D NET,ROUTE,DESTSUB=4

  IST097I DISPLAY ACCEPTED
  IST535I ROUTE DISPLAY 1 FROM SA 15 TO SA 4 225
  IST808I ORIGIN PU = ISTPUS DEST PU = A04NCP NETID = NETA
  IST536I VR  TP    STATUS   ER       ADJSUB  TGN  STATUS  CUR MIN MAX
  IST537I                     0            3    1  INOP
  IST537I  1   0    ACTIV     1          500    2  ACTIV3    7   5  15

  IST537I  5   2    ACTIV     3           30    1  INOP
  IST537I  6   0    INACT     6          500    1  ACTIV3
  IST537I  6   1    INACT     6          500    1  ACTIV3

  IST537I                    15                    UNDEF
  IST314I END

From subarea 15 to subarea 500, you have ER1, ER2, and ER6 defined.

Display the route from Host500 to A310NCP with A04NCP as the destination subarea. From Host500, issue the following command:

  D NET,ROUTE,DESTSUB=4

  IST097I DISPLAY ACCEPTED
  IST535I ROUTE DISPLAY 1 FROM SA 500 TO SA 4
  IST808I ORIGIN PU = ISTPUS DEST PU = A04NCP NETID = NETA
  IST536I VR  TP    STATUS   ER       ADJSUB  TGN  STATUS  CUR MIN MAX

  IST537I                    15                    UNDEF
  IST314I END

From subarea 500 to subarea 310, you have ER1, ER2, ER6, and ER7 defined.

Display the route from A310NCP to A04NCP. From Host500, issue the following command:

  D NET,ROUTE,ORIGIN=A310NCP,DESTSUB=04

  IST097I DISPLAY ACCEPTED
  IST535I ROUTE DISPLAY 1 FROM SA 310 TO SA 4 225
  IST808I ORIGIN PU = A310NCP DEST PU = A04NCP NETID = NETA

  IST314I END

From subarea 310 to subarea 4, you have ER1 and ER6 defined.

So, you can use either ER1 or ER6 to go from subarea 15 to subarea 4.

Display the route from A04NCP to A310NCP with Host15 as the destination subarea. From Host02, issue the following command:

  D NET,ROUTE,ORIGIN=A04NCP,DESTSUB=15

  IST097I DISPLAY ACCEPTED
  IST535I ROUTE DISPLAY 1 FROM SA 4 TO SA 15 225
  IST808I ORIGIN PU = A04NCP DEST PU = A15PU NETID = NETA
