Reusing removed VXLAN interfaces sounds good. 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

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.

Loopbacks and subinterfaces are deleted also from show interface. Thanks, Matej
