  "message": "ospfd: blackhole route removal for area range\n\nISSUE\n\nWhen an area range is created in which there the sub-area has routes that are\nsmaller than the range, an ABR creates a blackhole route to cover the range.\nWhen the range is removed, the blackhole route is not removed.\n\n--A----B----C---\n\nB is an ABR with A in area 1 and C in area 0.  If A advertises `10.2.0.0/30` and\n`10.2.0.4/30` and B is configured with `area 0.0.0.1 range 10.2.0.0/29` a\nblackhole is created on B (`blackhole 10.2.0.0/29 proto zebra`).  When the\narea/range is removed via the command line, the blackhole remains in existence\neven though the \"range\" route is removed from area 0 and the individual routes\nare propagated.\n\nPATCH\n\nThe reason for this behavior is that, prior to this patch, the range is deleted\nfrom the area\u0027s list, so when ospf_abr_manage_discard_routes() gets called,\nthere is nothing to clean up.  The patch removes the discard route as part of\nthe processing of the command line (ospf_area_range_unset()).\n\nSigned-off-by: JR Rivers \u003cjrrivers@cumulusnetworks.com\u003e\nSigned-off-by: Scott Feldman \u003csfeldma@cumulusnetworks.com\u003e\nReviewed-by: Shrijeet Mukherjee \u003cshm@cumulusnetworks.com\u003e\nSigned-off-by: David Lamparter \u003cequinox@opensourcerouting.org\u003e\n",
