Hello guys
I have a cisco ASR 903 router (IOS XE 15.4(3)S3) and i can't do something...
This's our scenary (you could see it in attached image):
The ASR sends packets by Layer3 interface Gi0/0/0, which is connected to a device that limit BW. The ousite port of this device returns to ASR's interface Gi0/0/2 (Layer 2) and then the ASR forwards the packet to ISP by interface Gi0/0/5 (Layer 2).
MY CONFIGURATION on ASR-903
interface GigabitEthernet0/0/0
description ASR-to-BW_LIMIT_DEVICE
ip address 10.10.10.129 255.255.255.128
interface GigabitEthernet0/0/2
description BW_LIMIT_DEVICE-to-ASR
service instance 2 ethernet
encapsulation default
bridge-domain 20
interface GigabitEthernet0/0/5
description ASR-to-ISP
service instance 2 ethernet
encapsulation default
bridge-domain 20
For outbound traffic works perfect. The problem happens when the traffic is coming back from ISP to ASR. For some reason, inbound traffic flows directly from interface Gi0/0/5 to Gi0/0/0. It means that inbound traffic doesn't flow trough Gi0/0/2 to reach Gi0/0/0.
Do you know about this situation?
Do you think that i need another configuration ?
Regards
:)

Do you have any BDI created in this router?. Can you share the configuration from the router?.
