Description Steven Walter 2018-06-15 20:04:10 UTC

Description of problem:

A new feature is available in 3.9 allowing the admin to specify a CIDR as part of the EGRESS_SOURCE. This allows the egress router to access the subnet and thus be able to issue ARP requests, etc. Full details are in DOC TEXT here:

https://bugzilla.redhat.com/show_bug.cgi?id=1527602


Version-Release number of selected component (if applicable):
3.9


Document URL: 
https://docs.openshift.com/container-platform/3.9/admin_guide/managing_networking.html#admin-guide-limit-pod-access-egress-router

Section Number and Name: 
Using an Egress Router to Allow External Resources to Recognize Pod Traffic

Thank, Steven.

I've created a PR for this:

https://github.com/openshift/openshift-docs/pull/10591

Looks like this came from Dan Winship, so I'll ask him to give an ack before I merge.

Dan, I added a footnote to each time the EGRESS_SOURCE value appears. Is there anything you'd like me to change?
