external ips - seems like handwaving in docs

[Just Marvin <marvin the cynical robot gmail com>]

Hi,

    https://docs.openshift.com/container-platform/4.2/networking/configuring-ingress-cluster-traffic/configuring-ingress-cluster-traffic-service-external-ip.html#nw-creating-project-and-service_configuring-ingress-cluster-traffic-service-external-ip .

    Step 4 seems like magic. When I do that on my local CRC install, I get this:

[zaphod oc6010654212 Downloads]$ oc get svc -n openshift-ingress
NAME                      TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)                   AGE
router-internal-default   ClusterIP   172.30.165.244   <none>        80/TCP,443/TCP,1936/TCP   18d
[zaphod oc6010654212 Downloads]$ 

    Which is what I would have expected to see. Where is that "router-default" entry coming from? I've added an external ip to the crc device, so I think I've met the pre-requisites. Whats the step that I'm missing?

Regards,

Marvin
