From 821755530e328182c885c98891af799926bd56bd Mon Sep 17 00:00:00 2001 From: JR Rivers Date: Mon, 24 Sep 2012 17:26:50 +0000 Subject: ospfd: ABR algorithm not propagating MAXAGE LSAs into area When a range (or sub-range) is deleted, the area is notified by propagating a MAXAGE LSA. This LSA stays in the database for a while to both insure propagation as well as in the off chance that it's useful in the near future. Unfortunately, the ABR algorithm was treating these MAXAGE LSAs as unchanged and not propagating them within the areas.
