[karamalla0406]

How to submit an issue

BGP daemon crashed when L2VNI is unconfigured with a "no vni xxxxx" command. This happens when the impport/export route-target for the VNI is not auo-derived. The crash is caused by the double freeing of the route-target obejcts.

Thread 1 "bgpd" received signal SIGABRT, Aborted.
