This is a scenario where the out-of-the-box hier_config does not work. Hier_config is agnostic to the OS, so it isn't going to understand that the ip address has to be re-applied when an interface adds or removes a vrf.
In this instance, you will need to create a remediation plan that you can side load. In the past, I've done this by creating python functions for specific use cases and calling the python functions as part of the remediation workflow.
Here is a basic example:
>>> host = Host("example.rtr", "ios")
>>>
>>> running = """
... interface Vlan480
... vrf forwarding TEST
... ip address 1.1.1.1 255.255.255.252
... """
>>> generated = """
... interface Vlan480
... ip address 1.1.1.1 255.255.255.252
... """
>>>
>>> host.load_running_config(running)
>>> host.load_generated_config(generated)
>>>
>>> interface_cfg = host.generated_config.get_child("startswith", "interface Vlan480")
>>> interface_cfg.children
[HConfigChild(HConfigChild, ip address 1.1.1.1 255.255.255.252)]
>>> remediation = host.remediation_config()
>>> remediation.children
[HConfigChild(HConfig, interface Vlan480)]
>>> remediation_interface = remediation.get_child("startswith", "interface Vlan480")
>>> remediation_interface
HConfigChild(HConfig, interface Vlan480)
>>> for line in interface_cfg.all_children():
... remediation_interface.add_child(line.text)
...
HConfigChild(HConfigChild, ip address 1.1.1.1 255.255.255.252)
>>> print(host.remediation_config_filtered_text({},{}))
interface Vlan480
no vrf forwarding TEST
ip address 1.1.1.1 255.255.255.252
Hallo!
where I try to change the vrf of an interface, ip_address gets deleted and would need to be reapplied.
how to achieve this with hier_config?
