ios_config IP assignment issues

Hi-

I have two different issues, although they are both related to IP address assignment via ios_config.

Issue 1 - Does not generate error when IP address inconsistent with netmask:

e.g.

  • name: Create port-channel interface
    ios_config:
    provider: “{{ cli }}”
    before: “default interface {{ item.interface }}”
    lines:
  • description MPLS to {{ item.desc }}
  • no switchport
  • ip address {{ item.address }} 255.255.255.252
    after:
  • no shutdown
    parents: interface {{ item.interface }}
    match: exact
    with_items:
  • { desc : Test, interface : Port-channel3, address : 172.30.0.60 }

In this example, the task runs fine:

TASK [Create port-channel interface] ***************************************************************************************************
changed: [6840-vss] => (item={u’interface’: u’Port-channel3’, u’address’: u’172.30.0.60’, u’desc’: u’Test’})

But there is no IP address on the interface, and when I do it manually it fails (as expected)

6840-VSS#sh run int po3
Building configuration…

Current configuration : 98 bytes
!
interface Port-channel3
description Test
no switchport
no ip address
end

6840-VSS(config)#int po 3
6840-VSS(config-if)#ip addr 172.30.0.60 255.255.255.252

Bad mask /30 for address 172.30.0.60

Issue 2 - Assignment of /31 addresses fails, although it actually updates the config.

Task is identical to above except netmask is 255.255.255.254

TASK [Create port-channel interface] ***************************************************************************************************
failed: [6840-vss] (item={u’interface’: u’Port-channel3’, u’address’: u’172.30.0.60’, u’desc’: u’Test’}) => {“command”: “ip address 172.30.0.60 255.255.255.254”, “failed”: true, “item”: {“address”: “172.30.0.60”, “desc”: “Test”, “interface”: “Port-channel3”}, “msg”: “ip address 172.30.0.60 255.255.255.254\r\n% Warning: use /31 mask on non point-to-point interface cautiously\r\n6840-VSS(config-if)#”, “rc”: 1}
to retry, use: --limit @/home/david/roles/portchannel.retry

When i do this manually:

6840-VSS(config)#int po3
6840-VSS(config-if)# ip address 172.30.0.60 255.255.255.254
% Warning: use /31 mask on non point-to-point interface cautiously

Thoughts?
