一、需求

有几台新上线的Juniper，需要批量配置下syslog,ntp,snmp基础配置

二、拓扑

三、实施步骤

1.读取配置并输出作为初步核查
2.把配置载入网络其中一台网络设备中，并做一个show | compare输出，然后做一个commit check核查，最后退出设备
3.输出一个提醒，要求输入yes 或者no。yes代表继续tasks,进入第4步;no代表退出playbook，终止程序
4.将配置输入到设备，并设定一个10分钟倒回时间
5.commit check 确认配置，停止倒回时间

四、脚本

1. 创建一个变量文件夹junos_config_vars

mkdir junos_config_vars

2.在变量文件夹里创建一个变量文件vsrx_vars.yml

nano junos_config_vars/vsrx_vars.yml

---
vsrx_config:
#系统基本参数配置
- set system syslog host 1.1.1.1 any any
- set system syslog source-address 192.168.62.44
- set system ntp server 192.168.62.254
- set system ntp source-address 192.168.62.44
- set snmp location "Shanghai China"
- set snmp contact "lisl"
- set snmp community public authorization read-only
- set snmp trap-group gingerdoc targets 192.168.62.253

3.编辑inventory文件

nano lisl_hosts

[junos]
junipervsrx02 junos_host=192.168.2.43
junipervsrx01 junos_host=192.168.2.44

4.编辑层次化变量组文件

nano group_vars/junos.yaml

---
ansible_connection: local
ansible_network_os: junos
ansible_user: admin
ansible_ssh_pass: juniper123

5.编辑剧本playbook：config.yml
