Doc Type:	Enhancement
Doc Text:	With this update, administrators are now able to view the state of High Availability routers on each node, and specifically, where the active instance is hosted. Previously, the High Availability router state information was not visible to the administrator; this made maintenance harder, for example, when moving HA router instances from one agent to another, or assessing the impact of putting a node in maintenance mode. This new functionality also serves as a sanity test and offers assurance that a router is indeed active on only one node. As a result, administrators may now run the 'neutron l3-agent-list-hosting-router <router_id>' command on a High Availability router to view where the active instance is currently hosted.

Description RHOS Integration 2014-10-16 00:05:40 EDT

Cloned from launchpad blueprint https://blueprints.launchpad.net/neutron/+spec/report-ha-router-master.

Description:

Highly available routers is a new functionality that was merged in the
l3-high-availability blueprint. HA routers are scheduled on multiple L3 agents
however the cloud operator has no way of knowing where the active instance
is.

None

Comment 4 Roey Dekel 2015-06-08 09:58:41 EDT

Verified on Kilo with:

Version-Release number of selected component:
---------------------------------------------
Puddle: 2015-06-02.1
python-neutronclient-2.4.0-1.el7ost.noarch
openstack-neutron-common-2015.1.0-1.el7ost.noarch
openstack-neutron-2015.1.0-1.el7ost.noarch
python-neutron-2015.1.0-1.el7ost.noarch
openstack-neutron-ml2-2015.1.0-1.el7ost.noarch

Reproduce steps:
----------------
1. Set up VRRP environment
2. Add an ha router
3. neutron l3-agent-list-hosting-router router1
4. Compare to state at the networkers

Results:
--------
As expected:
