Running OROUTED to Exchange RIP Routing Updates

Introduction

This document gives an example of the configuration required on the router and on the mainframe to exchange RIP routing updates through the use of the OROUTED procedure. OROUTED is a procedure which runs on the mainframe and which performs essentially the same function as when you run the ROUTED daemon on a UNIX host. OROUTED runs from either the OpenEdition/Multiple Virtual Storage (OMVS) address space or as a started task.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

This configuration was developed and tested with these software and hardware versions:

• Cisco IOS^® Software Release 12.1(2) with Mainframe Channel Port Adapter (XCPA) microcode xcpa27-7.

  This was the latest version of code released at the time, but these features should be supported in all currently maintained major versions of code.

• The router is a Cisco 7206 with a PCPA (Parallel Channel Port Adapter).

OROUTED requires these two configuration files on the mainframe in the OMVS address space, with environment variables that point to their location:

• export ROUTED_PROFILE=/etc/orouted.profile

• export RESOLVER_CONF=/etc/resolv.conf

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

For more information on document conventions, refer to the Cisco Technical Tips Conventions.

Background Information

In order to start OROUTED, issue these commands from within OMVS:

cd /usr/lpp/tcpip/sbin

orouted

On the MVS console, you can issue this command in order to find the process number of the OROUTED process:

d omvs,u=p390

Note:  p390 is the logon identification under which OROUTED was started.

You can also start the OROUTED process through job control language (JCL), as a started task. If you start it from OMVS, change the 520 port in the TCP/IP profile dataset to OMVS.

These are examples of the datasets:

/etc/orouted.profile
RIP_SUPPLY_CONTROL: RIP1
RIP_RECEIVE_CONTROL: ANY
RIP2_AUTHENTICATION_KEY:
/etc/resolv.conf
TCPIPJobName TCPIP
DomainOrigin cisco.com
domain cisco.com
Datasetprefix TCPIP
HostName P390
Messagecase mixed
