| Nir Magnezi | 2016-02-16 09:16:23 UTC | Doc Text | Cause: The fix for Bug 1215177 added the "garp_master_repeat 5" and "garp_master_refresh 10" options to Keepalived configuration. This created two issues: 1. Keepalived never stops spamming the network with garps. 2. Due to a Keepalived bug, instances lose their IPv6 default gateway. Consequence: IPV6 router is not working with VRRP Fix: The solution is to drop the repeat and refresh Keepalived options. This will fix the IPv6 bug but re-introduce bug 1215177. To resolve this, use the delay option instead. Result: Keepalived sends a GARP when it transitions to MASTER, and then it waits a number of seconds determined by the delay option, and sends a GARP again. We'll use an aggressive 'delay' setting to make sure that when the node boots and the L3/L2 agents start, we'll give the L2 agent enough time to wire the ports. | |

We'll use an aggressive 'delay' setting to make sure that when the node boots and the L3/L2 agents start, we'll give the L2 agent enough time to wire the ports. | Prior to this update, the fix for bug BZ#1215177 added the "garp_master_repeat 5" and "garp_master_refresh 10" options to Keepalived configuration. This resulted in two issues: 1. Keepalived never stopped broadcasting garps to the network. 2. Due to a Keepalived bug, instances lost their IPv6 default gateway. Consequently, it was determined that the IPv6 router was not working correctly with VRRP. This update resolves this issue by dropping the repeat and refresh Keepalived options. This fixes the IPv6 bug but re-introduces bug 1215177. To resolve this, use the delay option instead. As a result of this update, Keepalived sends a GARP when it transitions to MASTER, and then waits a number of seconds (determined by the delay option), and sends a GARP again. This uses an aggressive 'delay' setting to make sure that when the node boots, and the L3/L2 agents start, the L2 agent has enough time to wire the ports. |
