SAMPLE COMMAND OUTPUT

Virtual-Access1 is up, line protocol is up
  Internet protocol processing disabled
Virtual-Access2 is up, line protocol is up
  Peer address is 10.1.1.1
  Dialer interface is Dialer1

SUMMARY

The template file show_ip_interface for Cisco IOS does not cover all the possible options.

I did resolve this issue by adding, but not sure how you'd want to deal with this in the real code:

  ^\s+Peer address is (\d+\.\d+\.\d+\.\d+)
  ^\s+Dialer interface is Dialer(\d+)

STEPS TO REPRODUCE

output = """Virtual-Access1 is up, line protocol is up
             Internet protocol processing disabled
Virtual-Access2 is up, line protocol is up
  Peer address is 10.1.1.1
  Dialer interface is Dialer1"""
  
from ntc_templates.parse import parse_output
ip_interface = parse_output(platform="cisco_ios", command="show ip interface", data=output)

EXPECTED RESULTS

Parsed object for the output of the command.

ACTUAL RESULTS
