ospf & stub networks

im going through a lab on my ccnp on: Configuring a stub area and a totally stubby area

ive configured all the basics before starting the stub network part but I:

cant ping from sanjose3 router to captown?
- according to diagram lab
- sanjose3 has a /30 address
- captown has a /24 address
everything else is pingable except to and from these 2 routers & all connections show as "up" including "sanjose3 & captown"!!

1. should they be pingable or is the lab wrong?
2. if lab is right what have i missed in config

my lab says to do a "show ip route" after all routers have basic connectivity, showing more route connections, when all I can see is:

captown#sh ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route

Gateway of last resort is not set is subnetted, 1 subnets
C is directly connected, Serial0
C is directly connected, Loopback0

I know its to do with the "ip addresses" although I thought VLSM is used, no matter what subnet its on.  other than this I havent got a clue.

The LAB is wrong.

The Serial0/0 interface on the capetown router should be
