Configure ospf with neighbors on broadcast networks in buggy versions of
12.2

Check it...

(from an earlier GS post of mine)

You all realize we work with the "Microsoft" of the networking world. (does

Rack1R5#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Rack1R5(config)#router ospf 1

Rack1R5(config-router)#net 191.2.125.5 0.0.0.0 area 0

Rack1R5(config-router)#nei 192.2.125.2
