Bridging on IOS XE (ISR 1100 Series) ??

[jellybeanshiba]

Could any of you please tell me why I don't see the bridging related commands on IOS XE 16.6.6 (C1116-4P, IP Base) ?

C1116-4P(config)#interface Ethernet0/2/0
C1116-4P(config-if)#bridge?
% Unrecognized command
C1116-4P(config-if)#interface GigabitEthernet0/0/0
C1116-4P(config-if)#bridge?
% Unrecognized command
C1116-4P(config-if)#interface Vlan16              
C1116-4P(config-if)#bridge?
% Unrecognized command

try

bridge 1 route ip

Thank you very much for your comment, but unfortunately it doesn't seem to work...

  ibm          IBM protocol
  vlan-bridge  vlan-bridge protocol
! missing ieee

C1116-4P(config)#interface GigabitEthernet0/0/0
C1116-4P(config-if)#bridge-group ?

C1116-4P(config-if)#bridge?

! neither bridge-group nor bridge-domain

Hello,

IOS-XE doesn't support the legacy bridge groups, it uses BDI. Check the document below. IP Base should in theory be sufficient. Can you create service instances ?

Thank you Georg, I tried it and it seems like working, except for the VDSL2-Interface (Ethernet0/2/0) or the integrated switch. As I originally intended to bridge between the VDSL2-Interface and a routed interface or a Vlan interface, it didn't achieve anything in the end, but I'm glad to have learned that bridging is configured differently on IOS XE.

C1116-4P(config)#interface Ethernet0/2/0 ! The VDSL-Interface
C1116-4P(config-if)#service ?
% Unrecognized command
C1116-4P(config-if)#interface GigabitEthernet0/0/0 ! The «regular» interface.
C1116-4P(config-if)#service ?
  instance  Configure Ether Service Instance

C1116-4P(config-if)#interface GigabitEthernet0/1/0 ! The first port of the integrated switch.
C1116-4P(config-if)#service ?
% Unrecognized command
C1116-4P(config-if)#interface Vlan16 ! An VLAN-Interface.
C1116-4P(config-if)#service ?
  instance  Configure Ether Service Instance

Dear Georg,

I tried configuring the bridging on the C1100 platform again – Turned out, that I hadn't read the documentation you suggested as I should. Bridging is now working and I'm very grateful for your help. Thank you so much!

Hi!

I'm about to do the same thing - can I ask please what it was you were doing wrong as it looks like to me the service instance command should be available on all interfaces on this platform?

[jellybeanshiba]

Hi @scidoner,

Thank you for your reply. Unfortunately though, I don’t remember what the issue was, nor have I the bridging configuration in place anymore. But if you see the command service instance being accepted where you need, I don’t see any reason why it shouldn’t work. Go ahead and configure it as you need, I’ll be happy to have a look on your config if it won’t work

Best regards,

iichikocchi

Awesome thank you for your reply!!!

Just came here to say, the VDSL bridging works just fine on this platform

Hey guys,

I was wondering if anyone tried bridging a ISR C1117-4PLTE to bridge the LTE port to the GI0/0/0 ports?

I cant seem to follow these commands to get it working as I dont have the options displayed in this link:
