| Doc Text | Cause: the default L3 HA implementation, keepalived, sometimes flips master router instance to backup if it receives multiple SIGHUP signals in quick succession. Consequence: HA master router sometimes flipped to backup, disrupting L3 connectivity until the previous backup keepalived instance takes over. Fix: to work around keepalived behavior, Neutron L3 agent now throttles SIGHUP signals sent to keepalived to make sure keepalived has enough time to reload configuration without being disrupted with failovers. Result: L3 connectivity implemented via HA routers is not disrupted on router updates in quick succession (floating IP updates and such). | |||

Result: L3 connectivity implemented via HA routers is not disrupted on router updates in quick succession (floating IP updates and such). | Previously, the default L3 HA implementation (keepalived) sometimes flipped the master router instance to `backup` if it received multiple SIGHUP signals in quick succession. Consequently, L3 connectivity was disrupted until the previous backup keepalived instance took over. With this update, to work around this keepalived behavior, the neutron L3 agent now throttles SIGHUP signals sent to keepalived to make sure keepalived has enough time to reload configuration without being disrupted by failovers. As a result, L3 connectivity implemented using HA routers is not disrupted after router updates arriving in quick succession (for example, with floating IP updates). |
