Network Management

Hi,

I'm trying to look into the capabilities of Ansible and modifying configuration files for the 3810m. 
Is it possible to store an entire configuration file in YML format and load that? 

(if you can do this, could you please point me to an example configuration file?)

(my current configuration file has VLANs, OSPF, BGP, multiple ACLs (RACLs to be specific), routes, route maps, NTP, SNMP etc...) 

I've looked at the modules and it seems like you could just put all this stuff into a command module to some extent, but I'm really looking for a whole configuration file to load if possible. 

or 
Is it only possible to load an regular text configuration file using a Ansible command to copy the configuration file from another tftp server or something like that? 

Are there any best practices for network management with Ansible? 

Any information here would be great. 

Thanks!
