How static route works in this situation?

[xyingfei]

Hi guys. Here is a picture I have set up two static routes in R1 which are 10.10.10.2 & 172.168.2.2, while their administrative distance are default (1) , in this situation , I am so confused, why I can ping 10.10.10.2 from R1, but can't 172.16.2.2

Hello,

post your zipped Packet Tracer project (pkt) file. If the routers are password protected, also include the passwords.

Hello,

there simply is a typo in the IP address of Serial0/0/0 on R2. Change:

interface Serial0/0/0
ip address 172.168.2.2 255.255.255.0

to

interface Serial0/0/0
ip address 172.16.2.2 255.255.255.0
