1 Introduction

This document describes how to configure a Realm Routing Table (RRT) in the Diameter application for the following:

Authorization and Authentication Application Routing
Accounting Application Routing

The RRT contains routing information, which is used to decide how to process the incoming requests from a particular Diameter application.

The RRT must be configured for the following traffic cases:

When outgoing messages are sent to the realm
When the destination host is not specified
When the destination host is specified, but not present in peer table, that is, among the configured neighbor peers

1.1 Prerequisites

This section describes the prerequisites, which must be fulfilled before using the procedure.

1.1.1 Conditions

The following conditions must apply:

For configuration of Authorization and Authentication Application Routing, the appropriate routing information is known.
For configuration of Accounting Application Routing, the appropriate routing information is known.
An Ericsson Command-Line Interface (ECLI) session in Exec mode is in progress.

2 Procedure

To configure an RRT:

Navigate to the DIA-CFG-RoutingContainer Managed Object (MO), for example:
>dn ManagedElement=NODE06ST,XyzFunction=xyz,DIA-CFG-Application=DIA,DIA-CFG-StackContainer=abc,DIA-CFG-RoutingContainer=abc
Enter Config mode:
(DIA-CFG-RoutingContainer=abc)>configure
Create a DIA-CFG-Drt MO, for example:
(config-DIA-CFG-RoutingContainer=abc)>DIA-CFG-Drt=ericsson.com:abc:FALSE
Commit the settings:
(config-DIA-CFG-Drt=ericsson.com:abc:FALSE)>commit
Navigate to the DIA-CFG-RoutingContainer MO:
(DIA-CFG-Drt=ericsson.com:abc:FALSE)>up

Show the settings:

(DIA-CFG-RoutingContainer=abc)>show DIA-CFG-Drt=ericsson.com:abc:FALSE

The following is an example output:

DIA-CFG-Drt=ericsson.com:abc:FALSE
   DIA-CFG-AccReqContainer=accReqContainerName
   DIA-CFG-AuthReqContainer=authReqContainerName

Is it required to configure Accounting Application Routing?
- Yes: Continue with the next step.
- No: Proceed with Step 17.
Navigate to the DIA-CFG-AccReqContainer MO, for example:
(DIA-CFG-RoutingContainer=abc)>dn ManagedElement=NODE06ST,XyzFunction=xyz,DIA-CFG-Application=DIA,DIA-CFG-StackContainer=abc,DIA-CFG-RoutingContainer=abc,DIA-CFG-Drt=ericsson.com:abc:FALSE,DIA-CFG-AccReqContainer=accReqContainerName
Enter Config mode:
(DIA-CFG-AccReqContainer=accReqContainerName)>configure
Create a DIA-CFG-AppRouting MO, for example:
(config-DIA-CFG-AccReqContainer=accReqContainerName)>DIA-CFG-AppRouting=0:8
Set attribute action, for example:
(config-DIA-CFG-AppRouting=0:8)>action=4
Set attribute nodeIds, for example:
(config-DIA-CFG-AppRouting=0:8)>nodeIds="0:node12.ericsson.com#abc"
Set the optional attributes, as needed:
- autoFailback
- secondaryNodeIds
Commit the settings:
(config-DIA-CFG-AppRouting=0:8)>commit

Verify the settings:

(DIA-CFG-AppRouting=0:8)>show

The following is an example output:

DIA-CFG-AppRouting=0:8
   action="4"
   nodeIds
      "0:node12.ericsson.com#abc"
   secFailoverActive=false

Is it required to configure the Authorization and Authentication Application Routing?
- Yes: Continue with the next step.
- No: Proceed with Step 25.
Navigate to the DIA-CFG-AuthReqContainer MO:
>dn ManagedElement=NODE06ST,XyzFunction=xyz,DIA-CFG-Application=DIA,DIA-CFG-StackContainer=abc,DIA-CFG-RoutingContainer=abc,DIA-CFG-Drt=ericsson.com:abc:FALSE,DIA-CFG-AuthReqContainer=authReqContainerName
Enter Config mode:
(DIA-CFG-AuthReqContainer=authReqContainerName)>configure
Create a DIA-CFG-AppRouting MO, for example:
(config-DIA-CFG-AuthReqContainer=authReqContainerName)>DIA-CFG-AppRouting=0:8
Set attribute action, for example:
(config-DIA-CFG-AppRouting=0:8)>action=4
Set attribute nodeIds, for example:
(config-DIA-CFG-AppRouting=0:8)>nodeIds="0:node12.ericsson.com#abc"
Set the optional attributes, as needed:
- autoFailback
- secondaryNodeIds
Commit the settings:
(config-DIA-CFG-AppRouting=0:8)>commit

Verify the settings:

(DIA-CFG-AppRouting=0:8)>show

The following is an example output:

DIA-CFG-AppRouting=0:8
   action="4"
   nodeIds
      "0:node12.ericsson.com#abc"
   secFailoverActive=false

Navigate to the relevant DIA-CFG-RoutingContainer MO, for example:
>dn ManagedElement=NODE06ST,XyzFunction=xyz,DIA-CFG-Application=DIA,DIA-CFG-StackContainer=abc,DIA-CFG-RoutingContainer=abc

Verify the settings:

(DIA-CFG-RoutingContainer=abc)>show -r

The following is an example output:

DIA-CFG-RoutingContainer=abc
   routingContainerName="routingContainerName"
   DIA-CFG-Drt=ericsson.com:abc:FALSE
            DIA-CFG-AccReqContainer=accReqContainerName
         DIA-CFG-AppRouting=0:8
            action="4"
            nodeIds
               "0:node12.ericsson.com#abc"
            secFailoverActive=false
      DIA-CFG-AuthReqContainer=authReqContainerName
         DIA-CFG-AppRouting=0:8
            action="4"
            nodeIds
               "0:node12.ericsson.com#abc"
            secFailoverActive=false
