I thought all directly connected links are advertised, regardless whether
that interface is participating in OSPF or not.... ref Doyle Vol 1, pg
411... "The LSA's describe all the router's links,..." Am I interpreting
this incorrectly? Thanks.

Mike,
The network statement "network 152.1.1.1 0.0.0.0 area 0" defines OSPF
only on interface 152.1.1.1 but your BRI0 is 152.1.1.77.
And see my previous post about a point I just learned about - "show ip
ospf database" does _not_ show the contents of the database - it's just
a list of the Link State Advertisements.
Jonathan

Subject: OSPF Routes
Can someone please help determine why networks directly connected to R1
are not being entered in the OSPF database and therefore not being
advertised to R2. I thought all directly connected networks (less
loopbacks) are automatically advertised via the OSPF process running on
that router. Also, notice that R1 Loop1 and R2 Loop0 are in the ospf
database... why isn't R1 Loop0?
