Certain static routes not getting automatically applied at boot-time

Solution Verified - Updated -

Issue

  • We have static routes configured in a route-<interface> file in /etc/sysconfig/network-scripts, using the ADDRESS#=, NETMASK#=, GATEWAY#= format, and when restarting the network service, some of the routes get applied while some others don't. In the following example, the last route for the 172.24.6.0/24 network does NOT get added automatically:

    GATEWAY0=10.60.100.1
NETMASK0=255.255.255.0
ADDRESS0=172.24.4.0
GATEWAY1=10.60.100.1
NETMASK1=255.255.255.0
ADDRESS1=172.24.5.0
GATEWAY2=10.60.100.1
NETMASK2=255.255.255.0
GATEWAY3=10.60.100.1
NETMASK3=255.255.255.0
ADDRESS3=172.24.6.0
