  • 1.  Doubt about TCP/IP configuration in z/OS.

    I'm enrolled in mainframe networking course.

    It is not clear which Data Sets to use or which members are going to be edited. It is mentioned that there are two routing protocols (RIP and OSPF) but there are no examples...

    Can anyone clear up those doubts?

    It can be something simple like steps to set up z/OS equipment with a compatible router (RIPv2 or OSPFv2).

    "I think" that since TCP/IP is used (VTAM to implement SNA is too complicated for me even though I can use OSPFv2) it will be one part in MVS and one in Unix.

    :-)

    Thanks a lot.

    Hey Saul,

    Both routing protocols are implemented in a TCP/IP sub-task/address space: OMPROUTE.

    Check out the z/OS Communications Server: z/OS 3.1 Communications Server: IP Configuration Guide and z/OS Communications Server: z/OS 3.1 Communications Server: IP Configuration Reference manuals for details. 

    OMPROUTE can be run as an MVS started procedure, from the z/OS shell, or from AUTOLOG - your choice.  Personally I prefer to run it as an MVS started procedure because that's what I"m most accustomed to working with.  You should be able to find sample JCL for OMPROUTE in TCPIP.SEZAINST(OMPROUTE) (or whatever dataset name standard your installaing is using for TCPIP installation datasets).

    Hi Saul.  Although it is an older Redbook, there is a good description of routing on z/OS in the following link - https://www.redbooks.ibm.com/redbooks/pdfs/sg247532.pdf.
