Appendix A. Table of Lab Network Hosts and Groups

The following table summarizes the names of all valid hosts and groups included in the Ansible inventory that is used by hands-on activities in this course.

Table A.1. Valid hosts and groups in the inventory

Name	Type	Member of
`access-layer`	group	`all`
`border-routers`	group	`all`
`cloud-services`	group	`all`
`cs01`	host	`access-layer`, `border-routers`, `cloud-services`, `ios`
`ftp-server`	group	`all`
`ios`	group	`network`
`leaf01`	host	`access-layer`, `leafs`, `vyos`
`leaf02`	host	`access-layer`, `leafs`, `vyos`
`leafs`	group	`vyos`
`local`	group	`all`
`localhost`	host	`local`
`network`	group	`all`
`server01`	host	`servers`
`server02`	host	`servers`, `ftp-server`
`server03`	host	`servers`
`servers`	group	`all`
`spine01`	host	`border-routers`, `spines`, `vyos`
`spine02`	host	`border-routers`, `spines`, `vyos`
`spines`	group	`vyos`
`vyos`	group	`network`

Important

The group all is automatically created by Ansible. Do not create a group named all in your inventory file.

A sample inventory file will look similar to the following:

[user@host ~]$ cat inventory
[leafs]
leaf[01:02]

[spines]
spine[01:02]

[border-routers]
spine01
spine02
cs01

[access-layer]
leaf01
leaf02
cs01

[cloud-services]
cs01

[ios]
cs01

[vyos:children]
spines
leafs

[network:children]
vyos
ios
