Hi,
I have configured a bridge domain between two ports of router (Gi 0/1 and Gi 0/2) and also i have configured a BDI interface and assigned an IP address (192.168.1.1/24) to it. In the picture below, you can see my topology.
my problem is, the two router in below could not ping the BDI interface IP address.
Thank you so much for your help

check @Blue_Bird notes it for IOS and you have IOS XE but let see result.
if not work then can you share the config of both other routers?
note:- regarding @Blue_Bird note add the three command not only one.

Hello!
Could you paste the configuration? Which device are you using? If the ports are switch ports, why not use vlans?
