• [ ] Documentation enhancement (avd.sh)

Is your feature request related to a problem? Please describe. Sort of, we are migrating to EVPN/VXLAN and some of our existing OSPF areas are NSSAs. In order to migrate them easily, NSSA support would be great to have.

A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

There is no structured data in the router ospf configuration on the cli config gen for NSSAs.

Describe the solution you'd like

It would be great to have the support for:

• nssa nssa-only
• nssa no summary
• nssa default information originate
• nssa lsa7 filter

A clear and concise description of what you want to happen.

Describe alternatives you've considered

A clear and concise description of any alternative solutions or features you've considered.

add the following structured data as below (for example):

router_ospf: process_id: '1': nssa: (if nssa key exists, enable nssa e.g. area x nssa) nssa_only: <true | false> nssa_no_summary: '<true | false> default_information_originate: <true | false>

@ernestoherrerab Please add more details on nssa lsa7 filter. AVD supports summary-address currently. Please add more details about use case if that is not sufficient. I'd suggest opening a dedicated issue for that.

[ernestoherrerab]

@ankudinov That nssa lsa7 filter can be ignored. And only look at please: nssa nssa-only nssa no summary default_information_originate

Thank you for looking into it
