Problem :- Customer is not able to connect CPE from Director?

Error :- 

Solution :-  Check the VNF manager configuration on the Versa CPE to find director southbound IP is present. 

admin@PASSIVE-VRRP-cli(config)% show system vnf-manager                                            
ip-addresses [ 10.112.1.1/32 10.112.1.2/32 ];
vnf-mgmt-interfaces [ tvi-0/201.0 ];

If not,

To fix this we need to update correct Southbound IP ( IP used by branch to connect to director via netconf) of director to CPE VNF Manager configuration

admin@PASSIVE-VRRP-cli(config)% set system vnf-manager ip-addresses [ 10.112.1.1/32 10.112.1.2/32 ]
