Table 2: Known Issues in NorthStar Controller 4.2.3
Junos OS Release 18.2 and 18.3 PCEP reporting limitation: In Junos OS Releases prior to 18.4R2, Junos reports the SR LSP name only. The segment list path names (for multiple primary paths or secondary path) are not reported via PCEP. The implications for NorthStar Controller Release 4.2.x are:
When a user modifies device interface IP addresses resulting in ISIS adjacency or OSPF neighbor migration, there could be additional links created in NorthStar due to transient states being advertised into NorthStar.
For example, suppose an ISIS adjacency is formed between interface IP address of 10.11.11.1 and 10.11.11.2, and the user modifies the device interface IP addresses to 10.11.11.5 and 10.11.11.6. In NorthStar, there might be three links displayed, each representing the ISIS adjacency:
The original and transient adjacencies are harmless to NorthStar path computation, as they are in DOWN state. The user can manually delete them to clean up the topology view.
When learning P2MP LSPs from network devices, NorthStar will create the P2MP group associated with the P2MP LSP. The bandwidth and priority of the P2MP group, however, do not reflect the bandwidth and priority on the P2MP LSP.
