Bridge Config IOS XE 17.6

[william85ribeiro]

Hi, 
hope someone can help figure this out.
We've got a configuration that works fine for remote sites where we've got IOS Routers. We're going to start replacing them by ISR running ISO XE 17.6 or above.

I can't find a way to configure the following to the ISR
I know protocal IEEE isn't supported anymore and the ISR uses BDI instead.

The part I'm stuck is how to associate the bridge-domain to the ATM interface. 
The interfaces don't have bridge-domain under them to associate to it.

This is the config for an IOS Router

bridge irb
!
 bridge 1 protocol ieee
 bridge 1 route ip
!
 interface ATM0
 no ip address
 load-interval 30
 no atm ilmi-keepalive
 no shut
!
 interface ATM0.835 point-to-point
 bridge-group 1
 bridge-group 1 spanning-disabled
 pvc 8/35
 bridge-dot1q encap 10
 encapsulation aal5snap
!
 interface BVI1
 ip address X.X.X.X
 ip mtu 1492
 ip tcp adjust-mss 1452

I appreciate it if anyone has a clue how I can get it sorted.

Hello @william85ribeiro,

Interface BDI1 is used as the Bridge Domain Interface and is associated with the bridge group 1.

bridge irb
!
interface BDI1
ip address X.X.X.X 255.255.255.0
ip mtu 1492
ip tcp adjust-mss 1452
bridge 1 protocol ieee
bridge 1 route ip
!
interface ATM0
no ip address
load-interval 30
no atm ilmi-keepalive
no shut
!
interface ATM0.835 point-to-point
pvc 8/35
encapsulation aal5snap
bridge-group 1
bridge-group 1 spanning-disabled
bridge-dot1q encap 10
!

Hi M02@rt37 

Unfortunately... that's where my problem is. The IOS XE 17.6 doesn't have any bridge command under the interface.
See the attachment.

Device info:

C1117 - IOS XE 17.06.05 with ipbasek9, securityk9, and appxk9

Thanks.

try using service instance (which doesn't work on subinterfaces) so I'm not sure how it will work with the ATM0.835 (I've never used ATM interfaces).

interface ATM0

 service instance 1 ethernet

  encapsulation dot1q 10

  bridge-domain 1

!

I used the service instance to set up the bridging on ISR4331 and C8200 routers running IOS 17.6
