Parser and API unable to parse OSPF area 0 if not in IP Address format
Scenario: C8K (IOS-XE 17.9) connected with OSPF routing enabled on multiple interfaces in Area0
Issue: Genie parser is unable to read Area 0 when this is not in IP Format and raise an invalid IP exception
Tried with Parsers and API and both have the same behaviour.
The following commands has been tested: show ip ospf show ip ospf neighbor detail show ip ospf interface
How to replicate:
testbed = Genie.init("testbed.yml")
device = testbed.devices['C8K-01'] device.connect()
ospf = device.api.get_ospf_interfaces() print(ospf)

Troubleshooting: From the code https://github.com/CiscoTestAutomation/genieparser/blob/master/src/genie/libs/parser/iosxe/show_ospf.py#L1429 it seems that it tries to get the area of the ospf neighbour based on an IP format. However the area on the router for Area 0 gets converted to '0' by the IOS that is not a valid IP.
Reviewing the test for this function https://github.com/CiscoTestAutomation/genieparser/blob/master/src/genie/libs/parser/iosxe/tests/ShowIpOspfInterfaceBrief/cli/equal/golden_output_expected.py it seems is only being tested on the area using the IP format 0.0.0.8
Tested with 0.0.0.1 as Area and the parser works as expected
Hello stefanopilla,
I tried executing the command show ip ospf interface brief and i am not seeing the issue there and getting proper output as below,
{'instance': {'1': {'areas': {'0.0.0.0': {'interfaces': {'GigabitEthernet2': {'ip_address': '10.10.12.1/24', 'cost': 1, 'state': 'DR', 'nbrs_full': 0, 'nbrs_count': 0}}}}}}}
Kindly check and let me know.
Hi @sowmyadn010501 ,
I'm continuing to see this on multiple devices and IOS/IOS-XE version and not only in the lab environment.
I think the issue is only on the IOS/IOS-XE versions where the area gets converted from the '0.0.0.0' format to '0'.
As you can see in your output the area that the parser is pulling from the device is in the '0.0.0.0' format probably because the IOS version on your testing environment doesn't convert it to '0'. In my output provided above the area format on the ios is converted to '0' (even if I configured it to be 0.0.0.0). This happens only with area 0. No issues if area != 0.
I think that the solution would be to handle also the case where area is not in IP format and add the area 0 and 0.0.0.0 in the tests.
Here is another example from a production environment (CAT4506 with IOS-XE 15.2-7

Hi, As you mentioned about IOS/IOS-XE versions, can you tell me the specific version you are using?
Hi @sowmyadn010501 sorry for the delay on this one.
The IOS versions of the devices on which I face the issues are in my previous messages:
C8K (IOS-XE 17.9) CAT4506 with IOS-XE 15.2-7
Thank you
Hi, As you can take a look at below analysis, I used the output what you shared and ran the command using mock data and its being tested on the area using the IP format only and not getting converted to '0'.

Hi,
not sure with which data you're tried but the conversion is on the IOS side so the parsers is expecting to receive it into IPAddress format. If you spin up a C8Kv with IOS-XE 17.9 and you try to configure OSPF with area 0.0.0.0 the IOS-XE will convert it to '0' (you can see it from my output above) and then you will face the issue. Here is the output from another device on which I just faced the same issue:

As a proof that the problem is the format of the area received by the parser you can also run this simple script:
from netaddr import IPAddress, IPNetwork
area_ip = '0.0.0.0'
print(str(IPAddress(str(area_ip))))
area_no_ip = '0'
print(str(IPAddress(str(area_no_ip))))

**raise AddrFormatError('failed to detect a valid IP ' 'address from %r' % addr)
netaddr.core.AddrFormatError: failed to detect a valid IP address from '0'**
as you can see the error message is the same so a possibile solution might be a check that if the area is '0' is should be converted to '0.0.0.0' by the script.
Let me know if there's any additional information you need.
Hi, i tried with sample script you shared earlier as you can see in below screen shot i am getting it correctly and 0 has been converting in to into the ip format
Also can you share me the EXACT testbed device schema without the ip/port.
That is very strange... I tried with both netaddr version 1.0.0 and 1.2.1 (latest) and I'm still having the issue. Python 3.9.18.
What Python and netaddr version are you using?
here is the device schema in my testbed:
hostname:
alias: hostname
type: switch
os: iosxe
connections:
defaults:
class: unicon.Unicon
ssh:
protocol: "ssh"
ip: "x.x.x.x"
hostname: "hostname"
command: "ssh -l admin x.x.x.x -o KexAlgorithms=diffie-hellman-group1-sha1,[email protected],ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1"
arguments:
init_exec_commands: []
init_config_commands: []
credentials:
default:
username: admin
password: password
Hi, As for the python and netaddr versions i am using below versions, netaddr 0.10.1 Python 3.8.2.
Hi, we pyATS team only support netaddr until version 0.10.1. Can you please let me know whether you updated the netaddr version by yourself?
You are not responding; hence I am closing this ticket. I hope you are not facing this issue anymore, but if you are still facing the same issue, kindly let me know, I'll re-open the ticket. If you are facing any other issues, kindly open a new ticket. Thank you.
Hi @sowmyadn010501 ,
sorry for the delay but I have been out of office for the last 2 weeks. I didn't upgrade netaddr by myself but I found that I was using netaddr 1.0.0 (maybe it got upgraded by some other module I'm using). I downgraded to 0.10.1 and the issue is not present anymore and I'm getting the results as you.
I would still suggest to add a test for Area '0' in the tests given that we know that it will be an issue when pyATS will start to use netaddr version > 0.10.1.
Thank you for troubleshooting this with me. Appreciated your help.
