I ran into this UI bug the other day when I was trying to enable route redistribution on an Edge in a Secondary site of a cross-vCenter NSX deployment.

The Edge itself was deployed correctly, and configured to peer with a physical northbound router, however when I attempted to configure the route redistribution I was unable to do so.

Fortunately, the solution was simple - use the API.

Perform a GET operation to retrieve the current BGP configuration

1
GET https://{{nsxmanager}}/api/4.0/edges/{{edgeId}}/routing/config/bgp

Copy and modify the BGP section to include the redistribution settings you require

                                <ospf>false</ospf>
                                <bgp>false</bgp>
                                <static>false</static>
                                <connected>true</connected>
                            </from>
                            <action>permit</action>
                        </rule>
                    </rules>
                </redistribution>
                <gracefulRestart>false</gracefulRestart>
                <defaultOriginate>true</defaultOriginate>
            </bgp>

PUT the BGP section back to reconfigure the Edge

1
PUT https://{{nsxmanager}}/api/4.0/edges/{{edgeId}}/routing/config/bgp

The UI will still be disabled for route distribution, but the redistribution table will be populated, and BGP redistribution enabled.
