Doc Type: Bug Fix
Doc Text:
Cause: Bugs Consequence: When using the "static per-project egress IPs" feature, egress IPs may stop working in some circumstances if an egress IP is moved from one project to another, or from one node to another. Additionally, if the same egress IP is assigned to two different projects, or two different nodes, then it may not work correctly even after the duplicate assignment is removed. Fix: Bugs fixed Result: Static per-project egress IPs should work more reliably.

Description Dan Winship 2018-03-02 15:31:55 UTC 
Customer reported auto egress IP problems. Examination of logs and code reveals problems with (1) changing the EgressIP of a NetNamespace while its existing EgressIP is active, and (2) assigning duplicate EgressIPs to the same NetNamespaces or the same HostSubnets. Nodes will not always successfully recover from these situations (without being restarted) due to messed-up internal state

Tested with 3.10.0-0.47.0

The egressIP works fine with the conditions in comment#0.
