你可以看到bgp-information是一个列表变量（下一行以破折号开始）.所以你的最后一个任务应该是：

- name: Debug output
  debug:
    var: configs.stdout[0]['bgp-information'][0]['bgp-peer']

希望它能帮助

更新

我把你提供的输出，并在一个变量中定义它，这里是用来测试答案的剧本：

---
- hosts: localhost
  gather_facts: false
  vars:
    configs_stdout:
    - bgp-information:
      - attributes:
          xmlns: http://xml.juniper.net/junos/16.1R4/junos-routing
        bgp-peer:
        - active-holdtime:
          - data: '90'
          attributes:
            junos:style: detail
          bgp-bfd:
          - bfd-configuration-state:
            - data: disabled
            bfd-operational-state:
            - data: down
          bgp-option-information:
          - address-families:
            - data: inet-unicast inet-multicast inet-vpn-unicast inet-vpn-multicast inet-labeled-unicast inet6-labeled-unicast inet-mvpn
            attributes:
              xmlns: http://xml.juniper.net/junos/16.1R4/junos-routing
            authentication-configured:
            - data:
              - null
            bgp-options:
            - data: Preference LocalAddress AdvertiseInactive AuthKey LogUpDown AddressFamily Multipath Rib-group Refresh
            bgp-options-extended:
            - {}
            bgp-options2:
            - {}
            export-policy:
            - data: iBGP-POLICY
            holdtime:
            - data: '90'
            import-policy:
            - data: iBGP-IN
            local-address:
            - data: 174.68.232.31

  tasks:
  - name: Debug output
    debug:
      var: configs_stdout

  - name: Debug output
    debug:
      var: configs_stdout[0]['bgp-information'][0]['bgp-peer']

如果你运行PB，你将验证var: configs.stdout[0]['bgp-information'][0]['bgp-peer']是否工作。

我使用regex_replace找到了一个解决方案。

- name: Show BGP neighbor JSON output
      juniper_junos_command:  
        provider: "{{ credentials }}"
        commands:
          - show bgp neighbor 174.68.232.1
        display: json  
      register: configs

    - name: set fact
      set_fact:
        bgp_neighbor: "{{ configs.parsed_output | regex_replace('-', '_') }}"

    - name: Debug output
      debug:
        var: bgp_neighbor.bgp_information[0].bgp_peer[0].peer_state[0].data

    - name: Debug output
      debug:
        var: bgp_neighbor.bgp_information[0].bgp_peer[0].description[0].data 

    - name: Debug output
      debug:
        var: bgp_neighbor.bgp_information[0].bgp_peer[0].peer_id[0].data     

    - name: BGP Status
