Hi,
if you have requirement only for this flow then below workflow should work:
1) create centralized data policy for site_B which has below sequences:
#10 match data prefix source IP 1.1.1.1 destination IP x.x.x.x.x, action local-TLOC = public-internet
#20 match data prefix source IP 1.1.1.2 destination IP x.x.x.x.x, action local-TLOC = biz-internet
default action allow any
2) create centralized data policy for site_A which has below sequences:
#10 match data prefix source IP x.x.x.x.x destination IP 1.1.1.1 , action local-TLOC = public-internet
#20 match data prefix source IP x.x.x.x.x destination IP 1.1.1.1, action local-TLOC = biz-internet
default action allow any
Apply these policies per site direction from service_to_tunnel.
Note that, in order to have centralized data policy your vSmart(s) needs to be managed by vManage.
