Any new interface ( Router Link T1, Downlink, Uplink ) on T0 is not getting realized after upgrading.
This issue is only encountered if we are doing upgrade from Eclipse (2.3.x) to Firestar (2.5.x).
Execute Logical Router GET and PUT API X number of times without changing even single data of payload. Execute GET and PUT each time as revision changes.
Where X = ((Existing T0 router link ports before upgrade)/25) + 1. Let’s say if customer has 210 T0 router link ports before upgrade, it should trigger X = (210/25) + 1 = 9 activities of T0 before user creates any new interfaces on that T0.
GET
URI Path(s):
/api/v1/logical-routers/<logical-router-id> of T0
PUT
URI Path(s):
/api/v1/logical-routers/<logical-router-id>
This will cause the new provision of interface on T0 to fail and traffic will be impacted for those interfaces.
Existing interfaces on T0 and connected T1 will work and there is no impact of traffic .
