With Ansible playbooks for networking platforms, historically most of the networking modules require a provider argument per task (which supplied the connection type, username, password, etc).
With Ansible 2.5 (which you can install now, via the latest dev release) allows connection: network_cli as a top level connection which is supported by all the major Cisco platforms now (ios, nxos, iosxr). Also connection: netconf is supported on iosxr. The deprecation for provider won't begin with Ansible 2.5, and will take considerable time, so there will not be any rush to update playbooks.
The network_cli and netconf connection plugins will allow playbooks to look, feel and operate just like they do on Linux hosts. Also the error reporting is significantly improved, which will help a lot of people who were frustrated with changes to Ansible in 2.3.
Here is a quick example, the follow example will provide a 1-task playbook that performs a backup of the configuration for the host rtr1:
---
- hosts: rtr1
connection: network_cli
remote_user: admin
become: yes
become_method: enable
tasks:
- name: Backup configuration
ios_config:
backup: yes
