From 7c97bb50776e35369d36be52b568b0cb7fa5897c Mon Sep 17 00:00:00 2001 From: Clement Trebuchet Date: Thu, 12 Jul 2018 16:57:10 +0200 Subject: [PATCH] Devel ios vrf submode (#41659) * add submode features ipv4/ipv6 * add tests for submode * the parameters both_ * were not idempotent, in what is read in the configuration we have a list with 2 entries (import, export) while the input parameter has only one parameter which will be applied twice * add docstring to the ios_vrf module + provide a fix for: https://github.com/ansible/ansible/issues/41581 * complete tests * add missing description * fix KeyError for address-family ipv* * fix both_* tests * fix E231, W292, W293 * fix W293 * remove set has it doesn't preserve order of routes * fix E106 * remove ImportError: cannot import name OrderedDict * We should be able to mix the parameters for the routes targets , while remaining imdepotent. During the first implementation we did not take this into account, which did not correspond to the reality of the needs in production (to be able to use each parameter indifemently together) * remove epdb reference * FIX E111, E106 * FIX E302 * using loop produce a result who was not imdepotent * FIX E241 * fix: used pass intead of list --- lib/ansible/modules/network/ios/ios_vrf.py | 234 ++++++++++++++++-- .../network/ios/fixtures/ios_vrf_config.cfg | 64 +++++ .../units/modules/network/ios/test_ios_vrf.py | 79 +++++- 3 files changed, 350 insertions(+), 27 deletions(-) diff --git a/lib/ansible/modules/network/ios/ios_vrf.py b/lib/ansible/modules/network/ios/ios_vrf.py index 70fee2f745..9d01ff4de0 100644 --- a/lib/ansible/modules/network/ios/ios_vrf.py +++ b/lib/ansible/modules/network/ios/ios_vrf.py @@ -15,7 +15,6 @@ # You should have received a copy of the GNU General Public License # along with Ansible.
