The customer is running some services such as BGP, OSPF, RSVP, MPLS under logical-systems.
Need to confirm if a change on the name would cause any impact
Based on the lab done, all the mentioned protocols will flap after renaming the logical system:

And here is when I rename the logical system to Test1:
labroot@tacitus-re0# rename logical-systems Test5 to Test1
