Comments:
- Why did Shobana's route table at port 2 fail
even though it looked correct?
The table showed that the forwarding port for
192.168.1.64/28 was port 5.
(Wasn't it strange that the red commit needed
box did not showup even though she seemingly had
changed the value of the next hop field?)
The 5 had not been accepted by Java yet;
i.e., the focus was still on that field.
So, ping was succeeding by going directly
from port 2 to port 3 without going through the
p5-p4 link; i.e., the original default route
table entry was in effect.
Solution:
You should terminate every field with a TAB or
ENTER key to ensure that the field has been
accepted by Java.
- In some Java environments, moving the focus to
the first row of a multiple row entry requires
you to double-click instead of single-click.
This is usually only a problem if you try to modify
some of the GM filter fields.
