[c-nsp] OSPF Over FR

[cnsp at marenda.net]

- ensure you HUB will be DR by setting ospf priority on the interface level
  probably you which set this to "zero" on the spokes or a very low value.

- correct the network statements,
  i think it should read " network 192.168.123.0 0.0.0.255 area 0 "
  for the FR-interface , using the broadcast-emulation of frame-relay.

  Otherwise, one single network 0.0.0.0 0.0.0.0 area 0 
  should catch'em all...

- is the ospf interface type correct thru automagic ?

- and probably the frame-relay-"switch" is just broken.

  Test connectivity betweek each router-pair
  with loopback interfaces and static routes.
