This is due to a bug where allocated lif indices are not freed up correctly So, it might release a wrong lif index 
( which is still under use ) which is then getting allocated. This is the root cause for both the issues. 

1) vlan_port_create() -> entry exists error 
2) mpls_port_add() -> entry exists error

This is fixed via RLI and fix is only available from 24.3 onwards
