I suppose you should open a Jira to report the crash caused by this incorrect usage of a deleted VXLAN tunnel.

However I put deleted vxlan_tunnel interface UP, then assign it to a bridge domain and add pg interface to this bridge domain. When I sent a traffic to pg interface VPP crashes with build-root/install-vpp_lite-native/vpp/bin/vpp[10393]: received signal SIGSEGV, PC 0x7f8e63b7744d, faulting address 0xfffffffffffffffc in /var/log/syslog Regards, Matej From: John Lo (loj) Sent: 10. januára 2017 14:14 To: Matej Klotton -X (mklotton - PANTHEON TECHNOLOGIES at Cisco) <mklot...@cisco.com<mailto:mklot...@cisco.com>>; vpp-dev@lists.fd.io<mailto:vpp-dev@lists.fd.io> Subject: RE: [vpp-dev] Deleting VXLAN interface doesn't delete it from interface dump Yes, this is the expected behavior. These deleted VXLAN tunnels in the down state are placed in a pool so that it can be reused when more VXLAN tunnels are created later. On creating a VXLAN tunnel, any of these deleted ones are reused first, before new interfaces are created for the VXLAN tunnel.
