Hi all, while playing around with stp and pair interfaces and using exactly the same example as in man (4) pair
ifconfig pair0 up ifconfig pair1 rdomain 1 patch pair0 up ifconfig pair2 up ifconfig pair3 rdomain 1 patch pair2 up ifconfig bridge0 add pair0 add pair2 stp pair0 stp pair2 up ifconfig bridge1 add pair1 add pair3 stp pair1 stp pair3 up and while destroying/creating stp root pair interfaces with kern.pool_debug=1 and kern.splassert=2 i'm getting this traces splassert: bstp_notify_rtage: want 2
