Description of problem:
when testing: 4.16 feature and masquerade_subnet feature, i modified the internal masq,transit_sw,join_sw subnet, I can still see old route in NBDB.
Version-Release number of selected component (if applicable): 4.16
How reproducible:
Steps to Reproduce:
- Change the the internal OVN subnets.
- Then check the routes in NBDB:
- Network operator CR looks like:
[quickcluster@node-0 ~]$ oc get network.operator.openshift.io -o jsonpath="{.items[0].spec.defaultNetwork}"| jq { "ovnKubernetesConfig": { "egressIPConfig": {}, "gatewayConfig": { "ipv4": { "internalMasqueradeSubnet": "171.254.169.0/29" }, "ipv6": {}, "routingViaHost": false }, "genevePort": 6081, "ipsecConfig": { "mode": "Disabled" }, "ipv4": { "internalJoinSubnet": "100.66.1.0/16", "internalTransitSwitchSubnet": "100.90.1.0/16" }, "mtu": 8901, "policyAuditConfig": { "destination": "null", "maxFileSize": 50, "maxLogFiles": 5, "rateLimit": 20, "syslogFacility": "local0" } }, "type": "OVNKubernetes" }
