Proposal: Ansible Network Validated Content BGP Application

[rohitthakur2590]

Proposal:

• Validated content network.bgp enables the users to perform supported health_checks on bgp establishment.
• Enables the user to manage the BGP resources independent of platforms, so users can manage and configure BGP routes with operations like gather, deploy and persist, config.

Motivation

Describe the reasons for this proposal. Provide Network BGP Vaidated Content to perform BGP health checks and manage BGP resources.

Problems

• Build Brownfield Inventory: Users want to be able to get the facts for BGP resources and store it as host_vars thus enabling the capability to get facts for all the hosts within the inventory and store facts in a structured format which acts as SOT.
• BGP Resource Management: Users want to be able to manage the BGP global and BGP address family configurations.This also includes the enablement of gathering facts, updating BGP resource host-vars and deploying config onto the appliance.
• BGP Health Checks:: Users want to be able to perform health checks for BGP applications.These health checks should be able to provide the BGP neighborship status with necessary details.

Solution proposal

• ansible.bgp.run :
• This platform agnostic role enables the user to perform BGP health checks.Users can perfrom following health checks:
  • all_neigbors_up
  • all_neighbors_down
  • min_neighbors_up
• This role enables users to create a runtime brownfield inventory with all the BGP configuration in terms of host vars. These host vars are ansible facts which have been gathered through the *_bgp_global and *_bgp_address_family network resource module.The tasks offered by this role could be observed as below: Options:
