>From the below output, i need to extract only the IP 10.1.1.10 (it is ok if
the entire line starting from asterix is extracted).
I wrote below script and it seemed to work when i tested in regex101.com
but failing when i used it in playbook. What am i doing wrong? How can it
be improved?
*SWITCH COMMAND:*
CORE-SWITCH#sh ip route 0.0.0.0
Routing entry for 0.0.0.0/0, supernet
Known via "static", distance 1, metric 0, candidate default path
Redistributing via eigrp 500
Advertised by eigrp 500
Routing Descriptor Blocks:
* 10.1.1.10
Route metric is 0, traffic share count is 1
*SCRIPT:*
tasks:
- name: GATHER DEFAULT ROUTE INFO
ios_command:
commands: "show ip route 0.0.0.0"
register: default_route
- debug:
msg: "{{ default_route.stdout[0] | regex_findall('(.*)') }}"
*OUTPUT:*
ERROR! We were unable to read either as JSON nor YAML, these are the
errors we got from each:
JSON: Expecting value: line 1 column 1 (char 0)
Syntax Error while loading YAML.
found unknown escape character
The error appears to be in '/root/sample12.yaml': line 19, column 59,
but may be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- debug:
msg: "{{ default_route.stdout[0] | regex_findall('\* (.*)') }}"
^ here
We could be wrong, but this one looks like it might be an issue with
missing quotes. Always quote template expression brackets when they start a
value. For instance:
with_items:
- {{ foo }}
Should be written as:
with_items:
- "{{ foo }}"
Thanks,
Vikram
