Known Issues and Limitations in Juniper Cloud-Native Router Release 23.1
-
JCNR-3541: core-facing on access interface is not removing the interface from no local switching—When an access interface with the no-local-switching key enabled is configured to core-facing, then the no-local-switching functionality continues to be enabled on the access interface.
-
JCNR-3595: vf_isolated remains true for access interface even after deleting no-local-switching from BD after vRouter restart—Consider the following steps:
-
Deploy Juniper Cloud-Native Router having a workload access interface with no-local-switching enabled for the bridge domain.
-
Restart the vRouter and wait for it to be up.
-
Go to cRPD and remove no-local-switching functionality from the bridge domain.
The access interface continues to have no-local-switching key enabled while this should not be the case.
Workaround:
no-local switching works only for interfaces that have the interface-mode explicitly configured and are placed under the routing-instance and not the bridge domain. Therefore, the following configuration of the interface under the bridge domain which is done by the helm should be deleted,
set routing-instances vswitch bridge-domains bd1110 interface enp179s0f1v0
and the configuration shown below needs to be applied where the interface-mode is configured explicitly.
set routing-instances vswitch interface enp179s0f1v0 set interfaces enp179s0f1v0 unit 0 family bridge interface-mode access set interfaces enp179s0f1v0 unit 0 family bridge vlan-id 1110 set interfaces enp179s0f1v0 unit 0 family bridge core-facing

JCNR-3600: Redundant syslog ng container on helm upgrade—After a helm upgrade, the newly created syslogng pod continues to be in the pending state.
Workaround:
After the upgrade, delete the older syslogng pod manually by issuing the
kubectl -n jcnr delete <syslog-pod-name>
command. -
JCNR-3652: Agent pod missing "ss" causing the below Error in agent logs—The following error is visible in the contrail-vrouter-agent.log file. You can ignore this error as it does not affect the normal functioning of Juniper Cloud-Native Router.
[ERROR] [Category=Common, Task=http::RequestHandlerTask] No command output for ss -px | grep pid=166 | grep ESTAB | grep dpdk_netlink
