If the theory explain that when I have a "IP OSPF INTERFACE NETWORK TYPE" = NON-BROADCAST is necessary the NEIGHBOR command, to established adjacency.
Who can explain to me the following:
I have Two Routers (RouterA, RouterB) both are configure with
ip address 183.1.45.X 255.255.255.0 (RouterA = .5 and RouterB= .4)
ip ospf network non-broadcast
router ospf 1
network 183.1.45.X 0.0.0.0 area 45 (RouterA = .5 and RouterB= .4)
At this time everything is fine, nobody send hello messages.
When a configure the NEIGHBOR command over ONE of the router the OSPF ADJACENCY is established with FULL STATE; without the neccesary of configure it (NEIGHBOR COMMAND) on both routers.
Why is not necessary the NEIGBORG command on both routers?
I think that one router respond a OSPF hello always without verified if the source of the hello message is a "neighbor" configure under OSPF process; this may sound logical; but I need theorical information about that
I appreciate if anybody can help me.
