[TOPOPROCES-76] Updating a matched link src/dest to non-existing node does not remove it from overlay topology

Duplicate — Thu, 19 Oct 2017 21:29:16 +0000

The underlaying link does get updated properly, however the overlaying topology stays intact, with the old link info.

The attempt to remove the link from overlay topology produces this exception:
