Create IP trunk

This the workflow that brings the subscription from INACTIVE to PROVISIONING. The deployment of a new IPtrunk consist in the following steps:

  • Fill the form with the necessary fields:
    • SID
    • Type
    • Speed
    • Nodes
    • LAG interfaces with description
    • LAG members with description
  • WFO will query IPAM to retrieve the IPv4/IPv6 Networks necessary for the trunk. The container to use is specified in oss-params.json
  • The configuration necessary to deploy the LAG is generated and applied to the destination nodes using the Ansible playbook iptrunks.yaml This is done first in a dry mode (without committing) and then in a real mode committing the configuration. The commit message has the subscription_id and the process_id. Included in this, is the configuration necessary to enable LLDP on the physical interfaces.
  • Once the LAG interface is deployed, another Ansible playbook is called to verify that IP traffic can actually flow over the trunk ( iptrunk_checks.yaml)
  • Once the check is passed, the ISIS configuration will take place using the same iptrunks.yaml. Also in this case first there is a dry run and then a commit.
  • After this step the ISIS adjacency gets checked using again iptrunks_checks.yaml

The trunk is deployed with an initial ISIS metric of 90.000 to prevent traffic to pass.
