Hi, I am using kube-router for my network add-on. When I run the following, **route -n** to show the contents of my routing table on my master node, I can see the "kube-bridge" interface. However, when I reboot my master node, this kube-bridge interface disappears. What should I configure to persist this kube-bridge interface even after master reboot? What causes it to disappear? Does the bridge have to be manually re-created after reboot? What configuration is used to create this bridge? There is a file I see under /etc/cni/net.d/10-kuberouter.conf which is what my kube-router uses.
