The cause is that the prefix route was removed by in_scrubprefix() in the PRC_IFDOWN handler and never reinstalled upon PRC_IFUP because the reinstallation is done only for ifa passed to SIOCAIFADDR. Just calling if_up(ifp) looks too heavy to me because it causes extra pr_ctlinput() calls of each protocol, not only inetdomain, in order to recover the routes. What do you think about adding reinstalltion of the prefix routes in the protocol specific PRC_IFUP handler instead?
