Eduardo, I've added a note box to the suggested section: https://github.com/openshift/openshift-docs/pull/3004 Is the problem with a specific variable? I feel like it would be better placed within the table. Do you think there's a possible better placement for the note box? Thanks! The variable is "openshift_master_portal_net", so I'd say it would be better to move it where the variable description is. Any case, the box should say that by default, the docker0 network is that ip, but you can change it if you want but that's unsupported (in case it is) or the procedure to do it. Thx! Eduardo, Turns out there was something similar in the varible space already. I tweaked it to mention what you wanted included. Can I get an ack that this fulfills this BZ? https://github.com/openshift/openshift-docs/pull/3004/files Thanks! The thing is, the default docker0 network is the 172.17.0.1/16. I'd say:
+xref:../../architecture/additional_concepts/sdn.adoc#architecture-additional-concepts-sdn[{product-title}
+SDN]. This network block should be private and must not conflict with any
+existing network blocks in your infrastructure to which pods, nodes, or the
+master may require access to, or the installation will fail. Defaults to
+*172.30.0.0/16*, and *cannot* be re-configured after deployment.
+Please note that the *docker0* network bridge uses 172.16.0.0/16 by default,
+and you should avoid that too, or modify the docker0 network.
Cheers
Eduardo, Oops sorry. I'm a writer, so it might go without saying that all numbers look that same to me.. I've fixed to pretty much your suggestion, with a little rewording. WDYT? https://github.com/openshift/openshift-docs/pull/3004/files LGTM. Thx Brice!
