Section Number and Name: 
Scaling a MachineSet manually

Describe the issue: 
The default installation creates only one router. If you scale down your cluster, the node that hosts the router pod might be removed. In this case, you temporarily cannot access the web console and some other resources. After the router pod is redeployed to a different node, service will be restored.

Suggestions for improvement: 

It says that default router is 1 but the default router is 2.
$ oc get pod -n openshift-ingress
NAME                              READY     STATUS    RESTARTS   AGE
router-default-6f585b86bc-gv2h8   1/1       Running   0          166m
router-default-6f585b86bc-p6pcq   1/1       Running   0          166m

$ oc get relicaset -n openshift-ingress
NAME                                        DESIRED   CURRENT   READY     AGE
replicaset.apps/router-default-6f585b86bc   2         2         2         166m

I deployed ocp4 with ./openshift-install-latest unreleased-master-490-g0ddac41932688237c599cc8a7231d624a08dfc29 which is the latest source of openshift installer as of today(2019/March/4)

The PR's here:

If it's creating two routers, I think that we can remove the entire note.

Hongan Li, will you PTAL?
