Hi.
I´m configuring a new router ISR 4000, but i cannot find all needed commands for bridge feature.
Please your help if somebody know the equivalent commands for ISR 4000 series.
Thanks in advance.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Step by Step Bridge Group Virtual Interface (BVI) Configuration
Integrated Routing and Bridging configuration on Router1:
Router (config)#int fa0/0
Router (config-if)#bridge-group 1 NOT SUPPORTED
Router (config-if)#no shut
Router(config-if)#exit
Router (config)#
Router (config-if)#int fa1/0
Router(config-if)#bridge-group 1 NOT SUPPORTED
Router (config-if)#no shut
Router(config-if)#exit
Router(config)#
Create Bridge Group Virtual Interface (BVI) and configure the IP and Routing credentials.
Router1(config)#bridge irb
Router (config)#int bvi1
Router(config-if)#ip add 192.168.2.1 255.255.255.0
Router(config-if)#exit
Router(config)#bridge 1 protocol ieee NOT SUPPORTED "ieee"
Router (config)#bridge 1 route ip
Router(config)#

Here is the equivalent.
interface Gig0/0/1
service instance 25 ethernet
encapsulation dot1q 25
rewrite ingress tag pop 1 symmetric
bridge-domain 25
interface Gig0/0/2
service instance 25 ethernet
encapsulation dot1q 25
rewrite ingress tag pop 1 symmetric
bridge-domain 25
interface BDI25
ip address X.X.X.X 255.255.255.0
no shut

Since you don't mention Spanning-tree protocol in this syntax (vs. bridge X protocol ieee), is it a given? Or.....do you specify spanning-tree protocol somewhere else?
-----------------------
My4321-cir1(config)#bridge 1 protocol ?
dec DEC protocol
ibm IBM protocol
vlan-bridge vlan-bridge protocol
------------------------
See how this doesn't give me ieee protocol option? Please explain.

Did anyone ever address this issue?
Looking to setup STP on the ISR 4000.

No one answered, but I was able to piece it together.

That's awesome news! How did you get STP on the ISR 4000 with one port forwarding and one port blocking? I'm attempting to address this myself. Would appreciate learning the steps you took. Or if you could share sample configs?

Here is the basic config that I was originally looking for. This is how you essentially create Sub-Interfaces on a single physical interface and how you accommodate the dot1q tag.
bridge-domain 100
bridge-domain 200
bridge-domain 900

Hello, excuse me, support QoS ( policy IN , OUT ) in services instances? CIR ,MIR?.
