Summary:	[3.4] http traffic failures when accessing pod from outside of the cluster

Whiteboard:
Fixed In Version:		Doc Type:	Bug Fix
Doc Text:	Cause: The IP addresses for a node were not sorted. Consequence: When the first is chosen, it may be different from the last one used, so the IP address would appear to have changed. OpenShift would update the node -> IP mapping and that causes problems with everything moving from one interface to another. Fix: Sort the addresses. Result: The traffic flows correctly and the addresses don't change.	Story Points:	---

Comment 3 Meng Bo 2017-01-22 09:49:11 UTC

Tested with OCP build 3.4.1.0

Issue has been fixed.
No IP flip-flop in master log, and the route can be accessed without 503.
