BGP and Private Addresses

[net701]

I have a question about BGP and Private Addresses. This is from one of the Cisco labs and I have posted the physical setup here.

SanJose2(config)#router bgp 100
SanJose2(config-router)#no synchronization
SanJose2(config-router)#neighbor 192.168.1.6 remote-as 300
SanJose2(config-router)#network 201.0.0.0


ISP2(config)#router bgp 300
ISP2(config-router)#no synchronization
ISP2(config-router)#neighbor 192.168.1.5 remote-as 100
ISP2(config-router)#neighbor 172.24.1.18 remote-as 65000
ISP2(config-router)#network 202.0.0.0


CustRtr(config)#router bgp 65000
CustRtr(config-router)#no synchronization
CustRtr(config-router)#neighbor 172.24.1.17 remote-as 300
CustRtr(config-router)#network 203.0.0.0

One of the questions is if the SanJose2 router can ping the 203.0.0.0 network, and the answer is no. I believe it has to deal with private addresses but I don't fully understand because there are routes on SanJose2 and ISP2 for it to traverse to it without a problem.
