spfifc.C:

When a node’s link goes down, some of the trees may be disconnected. To indicate this, the parent-children tables at that node are updated. This is done in the destructor of the interface (link).

/* Set the parent-children tables to indicate the

* disconnected trees for each neighbor on the link

*/

ospf->set_flood_pctable(np);

ospf->hftb = 0; // Node goes into flooding mode
