From 9c923bcc9322c22220b574671c7b46f10008c614 Mon Sep 17 00:00:00 2001 From: "E. Scott Daniels" Date: Mon, 3 Aug 2020 09:22:20 -0400 Subject: [PATCH] Add ability to control route table req frequency This change introduces the RMR_RTREQ_FREQ environment variable which allows the frequency that RMR will send requests to the route manager to be externally controlled. Valid values are between 1 and 300 seconds inclusive. This change also closes a test initialisation issue causing unit test failures in the CI environment. Issue-ID: RIC-630 Signed-off-by: E.
