Re: Doubt regarding OSPF

Actually there is disagreement regarding Network Links connecting the both
router one router with Point-to-multipoint non broadcast list it as Stub

see the stored LSA in detail you will notice that advertising router is not
reachable due to that route will not come in to the routing table..
