Cisco ios_config replace: block not working

[Markus Rainer]

Hi,

I am using ansible 2.1.0.0

Module using: ios_config 

It seems that replace: block is not working.

Whenever changing one of my ntp_server ip addresses, only this ntp server is configured on my device.

All other NTS servers are deleted in config. 

For me it looks like, "replace block" is ignored.

variable: 

ntp_server_1: 78.46.40.125
ntp_server_2: 86.59.113.113
ntp_server_3: 93.185.134.30

playbook: 

- name: enable NTP
  ios_config:
    host: "{{ inventory_hostname }}"
    username: cisco
    password: cisco
    lines:
      - ntp server {{ntp_server_1}}
      - ntp server {{ntp_server_2}}
      - ntp server {{ntp_server_3}}
    replace: block
    before: ['no ntp']
    match: line

Best regards

Markus
