Hi Frog,
First of all, you can use clock signal where ever you want, actually it
depend of cable types, if you have DCE cable on FRSWITCH side, then give
clock signal at FRSWITH. Normally we don't use clock signal in real life,
because service providers would supply clocking.
AFAIR, you have no clock signal in your setup, give clocking at DCE cable
side.
Default OSPF network-type is non-broadcast for physical interfaces that has
frame-relay encapsulation (this means OSPF router will not send multicast
hello). Now you need to unicast your OSPF hello messages to you neighbor, or
you can change the network type with "ip ospf network-type point-to-point" ,
or point-to-multipoint according to topology. Below is two different
solution, you can use one of them. Neighbor comand is just required at one
side only.
1- router ospf 1
neighbor 192.168.18.1 ----> unicast hellos will be used
2- interface seial0/0
ip ospf network-type point-to-point ----> both end need to have same
timers and DR/BDR rules.
if you can't change both end's network-type then you have to tweak the
hello/hold timers accordingly ; broadcast and nonbroadcast situation.
Objects are what is unalterable and subsistent;
their configuration is what is changing and unstable.
So, you need PRACTICE, PRACTICE, AND MORE PRACTICE...

Hi Group,
Trying to configure simple Frame-relay switch (hub and spoke). OSPF is also
enabled on spoke routers

Router OSPF
network 192.168.18.0
Couple of doubt:
------------------------
The router are in the LAB environment, hence connected with DTE-dce cable
(as usual).
1) Do I need to configure the clock rate on frame-relay switch router or if
I configure clock rate on either on RTR-A or RTR-B ?
2) Concept - How OSPF will run between RTR-A and RTR-B
Thanks
Frog
