Bridge domain

[james.tribble]

I am converting from a 900 router to a 1111 router.  So the outside connection goes to our corp network.  I have a external DNS that is connected to the internal switch.  and they did a bvi.  moving to the new router it no longer supports BVI, so I have setup a bridge domain and a BDI inteface.  But cannot get the DNS server to talk to the inside and outside networks.  Depending on where I put the rewrite.  

interface Vlan60
no ip address
service instance 60 ethernet
encapsulation default
bridge-domain 60
!
!
interface BDI60
mac-address 0001.0002.0003
ip address 10.28.208.49 255.255.254.0
ip nat outside

interface GigabitEthernet0/0/0
no ip address
negotiation auto
service instance 60 ethernet
encapsulation default
bridge-domain 60

interface GigabitEthernet0/1/2
Description Ex-DNS
switchport access vlan 60
switchport mode access
switchport nonegotiate

Hello @james.tribble ,

you need to be consistent in configuration if you moved to bridge domains and BDI you don't need an unnumbered SVI interface Vlan 60

so:

no interface Vlan 60

!

then you need to configure the last interface as the previous one

do:

conf t

default interface giga0/1/2

interface giga0/1/2

service instance 60 ethernet
encapsulation default
bridge-domain 60

Hope to help

So I tried that and it didnt work I could get to the other sites but not internal  I have attached a diagram of the network.

Shouldn't the encapsulation be:

encapsulation dot1q 60
