Might help if you could check if the packet counts at ingress (port 1) & egress
(port 2) match. Similarly 3 & 4. And the mac entries seen on both vpp(s). ARP
req/rep tracing might also help.

Hi, vpp experts,
We are trying to make basic l2 bridge works within vpp.
We have two servers: r230 and r740, each of which has two phy nics. Two servers
are connected via cable. On each server, we bring these two nics into the same
vpp instance and put them into the same l2 bridge. We tried sending traffic
using ixia. However, ixia shows ping does not work.
I attached the topology, vpp conf files, startup conf file, and logs.
Please advise where we could make it wrong.
Thanks.
Chuan

On the 1st look everything look ok including the packet trace.
Can you try to clear counters* and enable packet trace on both instances.
Then send known number of packets and find put where drop happens by looking
into same outputs you already shared.....
* "clear int", "clear run", "clear trace"
