Proposed changes

    <network_services_keys.name>:
      - name: <str>
        redistribute_mlag_ibgp_peering_vrfs: <bool>
        vrfs:
          - name: <str>
            redistribute_mlag_ibgp_peering_vrfs: <bool>

See changed files for example of output.

• Finds all VRFs where redistribution has been disabled (default=True)
  • Add MLAG peer subnet to a list of disabled subnets
    • Respects custom IP algorithms and VRF specific pools.
  • Create a single prefix-list with all subnets.
  • Create a route-map denying the prefix-list, but permitting everything else.
  • Associate the route-map to redistribute connected only on VRFs where it has been disabled.

How to test

Added molecule coverage.
Asking customers to test.

@kmueller68 @c-po @perimore Please take a look and test if you can find time. Feedback is much appreciated.

Christian is on parental leave. He has implemented some kind of filtering of the MLAG peering subnet in the network.
I will have a look, at it, remove current filtering in the QA environment and try to test your implementation this week.

Tested against a custom repo with and without non-default settings under fabric_ip_addressing - works OK. Docs and Schema are good too.

[kmueller68]

tested it successfully against cutomer repo and eve-ng qual fabric.

      DC_OUTSIDE:
        vrf_vni: 14
        redistribute_mlag_ibgp_peering_vrfs: false
        vtep_diagnostic:
          loopback: 104
