From 99463849ebfa9de26aa8f333b0ab8df8ba75be43 Mon Sep 17 00:00:00 2001 From: Raimund Hook Date: Thu, 18 Jul 2019 10:53:04 +0100 Subject: [PATCH] Updated multi-region docs to include keepalived The keepalived_virtual_router_id should be changed from the default in the case of a multi-region deployment where the VIP of the different regions resides on the same subnet. This is not immediately clear - this change should make it more obvious.
