Question about OSPF and LSA type 3 behavior. Doyle in Routing TCP/IP vol 1:
"When another router receives a Network Summary LSA from an ABR, it does
not run the SPF algorithm. Rather it simply adds the cost of the route to
the ABR and the cost included in the LSA. A route to the advertised
destination, via the ABR, is entered into the route table along with the
calculated cost. This behavior - depending on an intermediate router
instead of determining the full route to the destination - is distance
vector behavior. So, while OSPF is a link state protocol within an area, it
uses a distance vector algorithm to find inter-area routes." (pg 474,475)
Please enlighten me.
TIA,
Ralph
