To change the IGP topology data source

Purpose

Perform this procedure to specify an IGP topology data source other than the default for the Network Map and Health and Object Troubleshooting dashboards.

See Table 13-3, IGP topology data sources for a list of the supported IGP topology data sources for each deployment type.

Note: It is strongly recommended that you contact technical support before changing the IGP topology data source.

Note: You must perform the procedure on the NSP cluster in each data center.

Note: release-ID in a file path has the following format:

R.r.p-rel.version

where

R.r.p is the NSP release, in the form MAJOR.minor.patch

version is a numeric value

Steps


1	Log in as the root user on the NSP deployer host.
2	Open a console window.
3	Open the following file using a plain-text editor such as vi: /opt/nsp/NSP-CN-DEP-release-ID/NSP-CN-release-ID/config/nsp-config.yml
4	Locate the section that begins with the following: `nspos:`
5	Edit the topologySource parameter in the igp subsection to read: Note: If no source is specified, the NSP uses the default for the deployment listed in Table 13-3, IGP topology data sources. `igp:` `topologySource: "source"` where source is one of the following: CPAM SDN, which specifies the VSR-NRC
6	Save and close the file.
7	Enter the following: `#` `cd /opt/nsp/NSP-CN-DEP-release-ID/bin ↵`
8	Enter the following: Note: If the NSP cluster VMs do not have the required SSH key, you must include the --ask-pass argument in the command, as shown in the following example, and are subsequently prompted for the root password of each cluster member: `nspdeployerctl --ask-pass install --config` `#` `./nspdeployerctl install --config ↵`
9	Log in as the root user on the NSP cluster host.
10	Open a console window.
11	Enter the following: `#` `helm uninstall assurance-tomcat -n $(helm list -A \| awk '/assurance-tomcat/ {print$2;exit}') ↵`
12	Return to the NSP deployer host console window.
13	Enter the following: Note: If the NSP cluster VMs do not have the required SSH key, you must include the --ask-pass argument in the command, as shown in the following example, and are subsequently prompted for the root password of each cluster member: `nspdeployerctl --ask-pass install --deploy` `#` `/opt/nsp/NSP-CN-DEP-release-ID/bin/nspdeployerctl install --deploy ↵` The configuration is applied.
14	Close the console window. End of steps
