[Openstack-operators] L3 HA Router

I figured this might be the case, but can you tell how I can locate the interface for the router namespace, if I do a ifconfig –a on the network node, I only see the br-* interfaces and the physical ones.

I assume, I’d need to take down one of the interfaces that keepalived is responsible for, but I’m not sure how to find them and make the right connection interface to router in order to choose the right interface to take down

Some work was done in that area however it was never completed.

You can issue an ugly failover by taking down the "ha" interface in the router namespace of the master with ifconfig down. But it's not pretty.

Best regards

Is it possible to perform a manual failover of HA routers between master and backup by any sensible means ?
