Hello folks,
We have Cisco C8200-1N-4T, it has 4 L3 ports GigabitEthernet0/0/1-3 and 4 L2 ports GigabitEthernet0/1/0-3
Could you please advise if it's possible to configure L2-domain between interfaces GigabitEthernet0/0/1 and GigabitEthernet0/1/0(trunk) to get the following topology:
Host1(10.10.10.1)<-Vlan10->Gi0/0/1[Cat8200]Gig0/1/0(trunk)<-Vlan10->[intermediate switch]<-->Host2(10.1010.2)
interface GigabitEthernet0/1/0
switchport mode trunk
end
Various configuration of gig 0/0/1 don't work, sort of
interface GigabitEthernet0/0/1
no ip address
negotiation auto
service instance 10 ethernet
encapsulation dot1q 10
bridge-domain 10
Is switching between built-in Ethernet WAN ports and NIM-ES2-4 switch ports possible?
Thank you in advance!

but that not full config
you need
bridge 1 protocol ieee bridge 1 route ip
to make router work as bridge.
add these command and check again

Thank you for reply!
Should it be vlan-bridge?
bridge 1 protocol ?
ast IBM protocol
dec DEC protocol
ibm IBM protocol
vlan-bridge vlan-bridge protocol

Configuring Transparent Bridging - Cisco
dec DEC protocol <<- I use this protocol in lab and success ping
but I must mention here something, in link I share there is note that mix ieee and dec protocol can lead to un predictable result.
so please read Link I share and then decide to config protocol dec.
thanks

MHM Cisco World,
Could you also please show at least e0/0, e0/1 configuration?
Have you made a specific configuration for BDI and Vlan interfaces?
Seeing the full test configuration would be great!
Thank you in advance!

Sorry, I meant e0/0, e 1/1, but the full configuration would be really useful
Thank you!

basically you can bridge domain using BVI as below example :
I have never used 8200 - as per the documentation looks it does not support it.
check the feature navigator based on the IOS code running (show version)
Another side if the Ethernet module is available why not use all in and out connections with the Ethernet switch module (GigabitEthernet0/1/0-3)? what is the challenge here ? (why you need to use only L3 ports ?

Hello balaji.bandi,
Yes, I read that artice and looks like C8200(IOS XE) does not support it, that's why I tried service instance and BDI
The challenge - Host1 provides the fiber connection, we can use SFP in Gig0/0/1. Switch ports are 1000BaseTX

For now, i can only think to get a Fiber to an ethernet adaptor to fix the solution you looking for. (if that device has limitation)
