Verify the static route management distance configured using the outbound Interface

The official CCNP teaching material emphasizes 0. In fact, no matter the outbound interface configuration or the Management Distance configured with the next hop address is 1. The experiment is as follows:
 
 
 
R1 (config) # ip route 1.0.0.0 255.0.0.0 serial 0/0
R1 (config) # do sh ip rou 1.0.0.0
 
Routing entry for 2.22.0.0/16
Known via "static", distance 1, metric 0 (connected)
Routing Descriptor Blocks:
* 1.1.1.2
Route metric is 0, traffic share count is 1
Directly connected, via Serial0/0
Route metric is 0, traffic share count is 1
 
 
 
 
 
R2 (config) # ip route 2.0.0.0 255.0.0.0 serial 0/0
 
R2 (config) # ip route 2.0.0.0 255.0.0.0 1.1.1.2
 
R2 (config) # do sh ip rou
