Now examine the following show flash command in Example 2-11, which was issued

Now examine the configuration in Example 2-12. Assume that there is now a route
to 134.141.88.0 and that the file c2500-j-l.111-9.bin is an IOS image in Flash memory.
What IOS do you expect will be loaded now?
134.141.0.0/24 is subnetted, 6 subnets
C 134.141.2.0 is directly connected, TokenRing0
R 134.141.3.0 [120/1] via 134.141.23.3, 00:00:15, Serial1
R 134.141.1.0 [120/1] via 134.141.12.1, 00:00:20, Serial0
C 134.141.12.0 is directly connected, Serial0
R 134.141.13.0 [120/1] via 134.141.12.1, 00:00:20, Serial0
[120/1] via 134.141.23.3, 00:00:15, Serial1
C 134.141.23.0 is directly connected, Serial1
