The problem for OSPF for adjencies to form is thath,the following
parameter MUST match for all OSPF interface connect togheter,
1) AREA ID
2) AUTHENTICATION
3) Network Mask
4) HELLO TIMER ------------------------------------------
5) Router Dead Interval
6) Stub Area Flag
for adjust the HELLO TIMER, you can use two solution:
1) You can use the "Ip ospf network type" under the interface and
automaticaly change the OSPF timer for the interface (for verify thath
"sh ip ospf interface")
2) You can adjust the OSPF Hello timer (ip ospf hello-intervall, ip
ospf dead-interval)
Other problem for OSPF adjencies is the Broadcast capabilities of the
interface, than for interface with no Broadcast capibilities it is
necessary define the neighbor because the hello are unicast, (neighbor
x.x.x.x)

You can set manualy the timer under the interface, if the time

I have not done Solies yet, but I know you do have to make all the timers
match in OSPF for adjencies to form, however I do not think that simply
making timers match is a solution to differeing OSPF network types. Is that
correct??
