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
