Bridge domain and Vlan

Hello!

I have Cisco 4331. Two SFP ports of this router connected to switches, (I need single brodcast domains in few vlans).

Also I have hwic module with switchports, switchport connected to cisco ASA as trunk.

I want to pass new VLAN from one switch to asa like:

Catalyst(Vlan 11 tagged) -> Cisco 4331 Gi0/0/0 (BDI configured) -> Gig0/1/1 (Trunk configured) -> ASA trunk interface

But traffic from bridge domain not passed to VLAN.

Part of config:

Cisco 4331

interface GigabitEthernet0/0/0

  service instance 11 ethernet
    encapsulation dot1q 11
    rewrite ingress tag pop 1 symmetric
    l2protocol peer cdp stp
    bridge-domain 11

 

vlan 11

interface Vlan11
  ip address 192.168.111.1 255.255.255.248

 

Catalyst connected to Gi0/0/0 4331

vlan 11

interface Vlan11
  ip address 192.168.111.2 255.255.255.248

 

interface GigabitEthernet0/25
  switchport mode trunk

 

What is wrong?

What I can connect Vlan to BD ?

Thank You!
