Xg1 publishing Moca IPv6 address for outside commn
Xg1 publishing Moca IPv6 address for outside commn

Reason for change: MOCA interface was getting global ip address
                   before the ESTB address. Processes were using the
                   first global interface for outside commn.
                   Now before assigning delegated prefix to MOCA we have
                   added a estb ip address check
Test Procedure: Ensure AV, IPv6 Address, AV at Xi devices
Risks: Low
