I was curious if someone could rationale why a network engineer would want to delete the local network route out of a route table.
For example if your route table looked comparable
Dest. Mask Gtwy Int Metric
127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 1 <-----Loopback
10.11.12.0 255.255.255.0 10.11.12.13 10.11.13.13 1 <-----local network (One to be deleted)
10.11.12.13 255.255.255.255 127.0.0.1 127.0.0.1 1 <------local host
10.11.12.255 255.255.255.255 10.11.12.13 10.11.12.13 1 <------local network broadcast
192.168.20.0 255.255.255.0 192.168.20.111 192.168.20.111 1 <-----local network
192.168.20.111 255.255.255.255 127.0.0.1 127.0.0.1 1 <------local host
192.168.20.255 255.255.255.255 192.168.20.111 192.168.20.111 1 <------local network broadcast
255.255.255.255 255.255.255.255 10.11.12.13 10.11.13.13 1 <------broadcast
Why would someone need to or want to manually delete out a local network route? it is to my understanding that 3 routes need to exist for basic connectivity via TCP/IP (besides the loopback and broadcast):
The local host
The local network
The local network broadcast
Any feedback is appreciated
