Junos OS: A user can configure a template in the router and map that template to an external controller. The router inherits the required configuration from the template and then provisions the external controller-initiated LSP. Unbinding the template from the external controller or changing template configuration can trigger deletion of the PCE-initiated LSPs (only LSPs which are using that particular template). Later, the LSPs are re-provisioned by the external controller.

Before performing a fresh install of NorthStar Release 5.0.0, you must use the ./uninstall_all.sh script to uninstall any older versions of NorthStar on the device.

PRPD does not remove prefixes (prefixes that have mapping) that were withdrawn by PCCs.

NA

NorthStar web UI Planner: Network spec files will be overwritten if an existing network name exists when using Save or Save As. A warning dialog appears if an existing name is found using Save As.

NA

NorthStar web UI Planner: If a user leaves the browser open without activity for a period of time, the session may get disconnected and not be able to fully resume later. As a result, some UI operations may not response properly. The workaround is to use the close network menu option and reopen the network.

NA

The Bandwidth Sizing task (Administration > Task Scheduler) is not able to collect the counters for LSPs on IOS-XR devices, so the bandwidth for these LSPs is not resized.

NA

For IOS-XR devices, you must run device collection before doing any LSP delegation. This applies to LSPs that were manually created using the router CLI.

NA

Changing a demand’s LSP binding directly from one LSP to another in one operation (without setting it to unbound first, then to the new LSP), the colored route insertion fails. NorthStar behaves as if it has the new LSP binding and colored route, but in reality the old colored route corresponding to the old binding is in the network. If you need to change the LSP binding of a demand with an existing binding, do it in two steps. First, clear the LSP Binding, and then set the LSP binding to the new LSP. This applies both to changing an LSP binding using the UI, and using REST API calls.

NA

NETCONF network information table update: when you delete an interface, the interface list is not updated in the Interface tab of the network information table.

NA

NETCONF SR-LSP bandwidth is displaying non-zero when adding an SR-LSP with a specific bandwidth.

NA

PRPD does not update Top N Prefixes properly.

NA

Normally, the web UI automatically switches to safe mode, and allows the admin user to log in when the Cassandra database is down. In this release, the automatic switch does not work. The workaround is to restart web server when you cannot log in to the web UI during a Cassandra failure.

NA

NorthStar Planner Desktop: There is no validation on the NorthStar Planner Destop when a license upload is attempted.

NA

The privateForwardingAdjacency (a pair of binding SID SR LSPs from A->Z and Z->A) logical link could be marked as down after the TopoServer process is restarted. The current workaround is to run a Device Collection task in the Task Scheduler, which would restore the correct status to the privateForwardingAdjacency logical link. This issue will be addressed in the next release.
