Pyats OSPF feaure objects

aidariys5 — Sun, 24 Apr 2022 08:36:38 GMT

Hello,

What is the proper way to add network to OSPF on router via Feature on Pyats?

from genie.libs.conf.ospf import Ospf

I cannot find method "add_network" but it is specified in Ospf feature model.

@aidariys5 Get the pyATS Library functionality that you need to create each feature, for example

from genie.conf.base import Interface
from genie.libs.conf.ospf import Ospf
from genie.libs.conf.isis import Isis
from genie.libs.conf.rip import Rip

Hope this helps.

HI, thanks for reply. Let me bring more context. I'm trying to add network to ospf (like: network 1.1.1.0 0.0.0.255 area 0)

For example, I can specify instance and area_id:

from genie.libs.conf.ospf import Ospf
r1_ospf.instance = '1'
r1_ospf.area_id = '0'

But I cannot add network, such options is simply not available but probably I'm missing something.

If check https://pubhub.devnetcloud.com/media/genie-feature-browser/docs/_models/ospf.pdf, then you will find these two options:

area_network

area_network_wildcard

Late answer: If your device type is NXOS the model does not support that
It is supported for IOSXE as you can see here
https://github.com/CiscoTestAutomation/genielibs/blob/master/pkgs/conf-pkg/src/genie/libs/conf/ospf/iosxe/tests/test_ospf.py#:~:text=an1%20%3D%20AreaNetwork,(an2)
Try these

from genie.conf import Genie

from genie.conf.base import Testbed, Device

testbed = Testbed()

Genie.testbed = testbed

dev1 = Device(name='PE1', testbed=testbed, os='iosxe')

vrf = Vrf('VRF1')

dev1.add_feature(vrf)

ospf1 = Ospf()

dev1=device

ospf1.device_attr[dev1].enabled = True

ospf1.device_attr[dev1].vrf_attr[vrf0].instance = '30'

ospf1.device_attr[dev1].vrf_attr[vrf0].enable = True

ospf1.device_attr[dev1].vrf_attr[vrf0].router_id = '3.3.3.3'

an2 = AreaNetwork(device=dev1)

an2.area_network = '192.168.1.1'

an2.area_network_wildcard = '0.0.0.255'

ospf1.device_attr[device].vrf_attr[vrf].area_attr['0.0.0.1'].add_areanetwork_key(an2)

device.add_feature(ospf1)

print(device.build_config(apply=False))
The above will work
If you change
dev1 = Device(name='PE1', testbed=testbed, os='iosxe')
to
dev1 = Device(name='PE1', testbed=testbed, os='nxos')
The resulting config won't show the network statement which you could use to activate OSPF on multiple interfaces in one shot> This does not work on NXOS
