XRv and CSRv Packet drops

[obattal]

Hello,

I have a test topology that includes mostly vm xrv9000 (powered on esxi as virtual machines). All of the routers can form IS-IS neighbor and able to ping every Ip on the lab network. Traffic generators (Trex/iperf3/scapy) are connected to the routers to simulate traffic. Traffic generators interfaces which are connected to the lab can ping each other and Ip addresses of the routers. No packet loss on ping, but the traffic created by the generators have nearly %90 loss.

To troubleshoot the routing issues, I have connected both traffic generator interfaces to only one router (directly connected interfaces/no need for extra routing protocol). Traffic drop rates are the same.

The tests that I have done can be summarized as below:

XRv9000 as vm esxi (7.3.1)

XRv9000 on EveNG (7.1.1)
Csr1000v as vm esxi (Virtual XE Software 17.03.02)

C8K on EveNG (Virtual XE Software 17.06.01a)

I have checked the packets dest/src, Mac/IP addresses and everything seems to be in order.

No crc, input or output drops on interface counters. No log corresponding the excessive drops.

Thank you in advance.

Hello @obattal,

This is an interesting question I don't have the answer to. Please post it here as well:

I think the Network Management and/or Routing sections would be best.
