Background: several boxes sit behind dynamically changing uplinks. The boxe= s are identified via dynamic DNS entries containing the NIC's MAC address at my dyn DNS prov= ider. A prerequisite is to configure the if_bridge() in question to inherit the/a (= persistent) MAC of a/the first inherited NIC. In my case, this part works without flaw. net.link.bridge.pfil_bridge When it comes to obtain an IPv6, CURRENT, in contrast to 14-STABLE, fails t= o set the host part according EUI-64. The resulting 64 host bit, which are considered to contai= n the 48 bit of the MAC, do contain anything but not anything similar to ANY of the attached NI= C/NICs.=20 For the record, here the sysctl settings changing default settings of OIDs = involving bridge (according to some docs when jails share epair() devices on that bridge): [...] net.link.bridge.inherit_mac=3D1 net.link.bridge.pfil_local_phys=3D0 net.link.bridge.pfil_member=3D0 net.link.bridge.pfil_bridge=3D0 net.link.bridge.pfil_onlyip=3D0 [...] I do not see the described (mutual) misbehaviour on 14-STABLE and or 14.2-R= ELENG. So the negative effect of this is that the hosts in questions are not acces= sible/known anymore to the net. A bug or a "feature (due to simple dumb misconfiguration)?
