Bridge interface is not working with vlan

Question

Dear Team, 
 
 We have to add two interface as a bridge - like A1 and A2 with sub interfaces (Vlan interface). 
 
 Below are the configuration steps which I had created yesterday for bridge interfaces- 
 
 1. Created Zone (Common ZONE) 
 2. having created Zone, added vlan in ZONE 
 3. after that I added port A1,A2 in bridge interface with Common ZONE. 
 Communication was not happing. 
 As I think there will be no policy required for bridge interface. 
 
 Even though I had gone through below documents but couldn't understand properly. Is there anyone who share any article or scenario with an example.

 Thank you.

In a bridge you will need firewall rules to allow traffic to travel from one port to the other (and back). So make sure to allow traffic using a firewall rule something like: 
 source: common zone destination: common zone service: any (or be more restrictive if necessary) Allow
