We have two device R1 and R2 running FreeBSD 9.2, on R1 we have set an ipv4 address for lo1:
Then add a route to R1 in R2:
Now we have access to R1 in R2, so ping is working. In this stage if we shut down lo1 the ping is still works:
The expected behavior is that we don't have to access lo1 after shutdown(ping don't work). FreeBSD 12.2 is also tested with the same result.
Question: Is this OK or a bug?
R1#: sudo ifconfig lo1 192.168.80.80
Then add a route to R1 in R2:
R2#: sudo ip r add 192.168.80.80 via 192.168.12.15
Now we have access to R1 in R2, so ping is working. In this stage if we shut down lo1 the ping is still works:
R1#: sudo ifconfig lo1 down
The expected behavior is that we don't have to access lo1 after shutdown(ping don't work). FreeBSD 12.2 is also tested with the same result.
