Overbroad Summary Route Blackhole
A routing cleanup made one newly acquired subnet disappear behind an overbroad summary.
シナリオ
Since Ironwood Motors consolidated its branch routes, a newly acquired subnet next door has become unreachable while older branch networks still work. The route table looks tidy, but traffic for the new network is being absorbed by a broader path than intended. Restore reachability to the acquired subnet without removing the valid summarized coverage for the other branches.
