Hi Marcos, I'm not sure what you're asking here. Reinstalling VPP should give you the same outcome.
The log you provided, points to vnet[2669]: #2 0x00007f1e6cb16f11 ip4_lookup_node_fn + 0xad1. To troubleshoot further, run gdb on the core file # gdb <path_to_vpp> <path_to_core> You may need to install the debug rpm of VPP, vpp-dbg, but do not run this file in production. My experience is that if you run the debug image outside of a lab, it will likely crash. root@ae2a2e85c5d4:/vpp/src# grep -r "ASSERT (0)" * | wc -l 127 On Thu, Dec 24, 2020 at 1:11 PM Marcos - Mgiga <mar...@mgiga.com.br> wrote: > Hi Paul, > > > > Ok, I will get the core file, but is this situation unusual ?
