Re: [vpp-dev] VPP crashes using bvi interface
Yes we need the bvi part for routing.Following is journalctl -xe when vpp crashes:May 24 05:51:57 localhost.localdomain sudo[40264]: pam_unix(sudo:session): session opened for user root by root(uid=0)May 24 05:51:57 localhost.localdomain sudo[40264]: pam_unix(sudo:session): session closed for user rootMay 24 05:53:32 localhost.localdomain vnet[40086]: /root/vpp/src/vlib/log.c:153 (vlib_log) assertion `vlib_get_thread_index () == 0' failsMay 24 05:53:32 localhost.localdomain vnet[40086]: received signal SIGABRT, PC 0x7f6db850d207May 24 05:53:32 localhost.localdomain vnet[40086]: #0 0x7f6db9ec4fc2 unix_signal_handler + 0x24cMay 24 05:53:32 localhost.localdomain vnet[40086]: #1 0x7f6db97bb5d0 0x7f6db97bb5d0May 24 05:53:32 localhost.localdomain vnet[40086]: #2 0x7f6db850d207 gsignal + 0x37May 24 05:53:32 localhost.localdomain vnet[40086]: #3 0x7f6db850e8f8 abort + 0x148May 24 05:53:32 localhost.localdomain vnet[40086]: #4 0x00407811 vhost_user_unmap_all + 0x0May 24 05:53:32 localhost.localdomain vnet[40086]: #5 0x7f6db92b823f debugger + 0x1cMay 24 05:53:32 localhost.localdomain vnet[40086]: #6 0x7f6db92b867a _clib_error + 0x2d2May 24 05:53:32 localhost.localdomain vnet[40086]: #7 0x7f6db9e56287 vlib_log + 0x2ceMay 24 05:53:32 localhost.localdomain vnet[40086]: #8 0x7f6d73300f5e snat_det_in2out_node_fn + 0x170fMay 24 05:53:32 localhost.localdomain vnet[40086]: #9 0x7f6db9e67122 dispatch_node + 0x2b8May 24 05:53:32 localhost.localdomain vnet[40086]: #10 0x7f6db9e67702 dispatch_pending_node + 0x372May 24 05:53:32 localhost.localdomain vnet[40086]: #11 0x7f6db9e69394 vlib_main_or_worker_loop + 0x8fdMay 24 05:53:32 localhost.localdomain vnet[40086]: #12 0x7f6db9e69bb0 vlib_worker_loop + 0x2cMay 24 05:53:32 localhost.localdomain vnet[40086]: #13 0x7f6db9e9bc8e vlib_worker_thread_fn + 0x120May 24 05:53:32 localhost.localdomain vnet[40086]: #14 0x7f6db92db524 0x7f6db92db524May 24 05:53:32 localhost.localdomain abrt-hook-ccpp[40282]: Process 40086 (vpp) of user 0 killed by SIGABRT - dumping coreThe crash happens when traffic is forwarded through the path.

Re: [vpp-dev] VPP crashes using bvi interface
Hi Uzzam, I have already tried using the command 'sudo vppctl set interface l2 bridge loopX 1 bvi' but the vpp crashes after few seconds. Can we see a back trace, please? While on the other hand when I use the command 'sudo vppctl set interface l2 bridge loopX 1', loop1 does not receive traffic. So you need the ‘bvi’ part /neale Following is the diagram of our architecture: [cid:607bf4bf1198454881731ffbdd203f61@Open-Xchange] Let me know how I can prevent bvi mode from crashing.
