Hello

I encounter a strange behaviour configure a basic bridge configuration

Two RARE/Freertr machines are connected: DAV0101 (DPDK) and DAV0001 (WEDGE)

1/ I configure IP the 2 interfaces and ping worked fine so it seems the interface hardware work fine

2/ I configure a bridge 1 with bvi1 interface - I cannot ping from the Wedge bvi1 the DPDK bvi1 interface

2.1 / Capturing the packet on the 2 physical interfaces. I can see that DPDK machine received the ICMP Echo request packet and answer a Echo reply. But on the Wedge it seems to not receive the packet. see the pcap at https://filesender.renater.fr/?s=download&token=04803078-bb70-4dbe-b99e-1f6b55a8df52
It seems that the Wedge cannot 'use' and/or 'store' the APR answer of the DPDK machine 

2.2/ But using show bridge (see screenshot below), I can see that Ethernet MAC addresses of the 2 bvi interfaces are present 

I put my 2 configurations (hoping that there are not obvious misconfiguration). I do not declare the sub interface in server p4lang. is it correct?

Any idea to debug this ?

Thank you
Xavier
