*******Site list Approach/Thought Process****************
So lets define site list ABC (11,12, 13) which have site id of site A.B,C as OMP-tag is common for all of them .
Lets define other Site list DC (100) , which will have only site id of DC .
site-list ABC
site-id 11-13
!
site-list DC
site-id 100
************Control Policy Approach/ Thought Process*************

Match : on Site-list and any prefix from site A , B, C
