Symptoms

Scenario: Running an OS replacement procedure from CentOS to SUSE on a system with configured static routes.

Impact:

  • Connectivity issues appear, and static routes must be reconfigured manually.
  • Potential data unavailability

Cause

Due to a software issue, the OS replacement process fails to retain static routes causing them to be removed once the operation completes. 

Resolution

To add a permanent static route, edit the following file:

/etc/sysconfig/network/routes/ifconfig.bondX.<replication_vlan>

 Add the static route, using the following format:

  
<destination-network>/<netmask> <source replication gateway-ip> - <interface>

 

Example:
Run the following command if replication Virtual Local Area Networks (VLANs) 161 and 162 are on interfaces eth3 and eth5, having Network 192.168.80.0/24 and 192.168.82.0/24 respectively:

echo "192.168.80.0/24 192.168.76.254 - eth3" >> /etc/sysconfig/network/routes/ifconfig.bond0.161
echo "192.168.82.0/24 192.168.78.254 - eth5" >> /etc/sysconfig/network/routes/ifconfig.bond1.162

Use the following path and file names if the following error appears: "/etc/sysconfig/network/routes/: Not a directory"

echo "192.168.80.0/24 192.168.76.254 - eth3" >> /etc/sysconfig/network/ifroute-bond0.161
echo "192.168.82.0/24 192.168.76.254 - eth5" >> /etc/sysconfig/network/ifroute-bond0.162

Reboot the node or run a network restart by running the following command for the change to take effect:

systemctl restart network.service

Once routes are added and the network service restarts, validate that the static route is configured and accessible (for example, through a ping command).
