Author will use six switches and four PCs to simplify the testing, because the
purpose of this simulation
just to see
how fast that the
link can
goes back
up.
If
author used the topology in figure 5.2, the topology can be so mesh up and it will
be
hard
to
be
seen
and
so
complex.
That
is
the
reason
of
just
choose
a
simple
topology to test the clustering (mesh).
Figure 5.8 Pretend to be clustering
In the
figure above, both switch 5 and switch 6 have 2 VLAN, which are
VLAN
10
and
VLAN
20.
The
way
it
was
simulated
to
test
the
fault
if
condition
that
author will cut the switch one by one and let see
in the ping,
how
the packet will
react
if there
is a switch off.
The simulation
has captured that the route that has
been determined by default that when PC 1 want to go to PC 3 is through switch
5
switch
2
switch
3
switch
6.
The
route
has
been
determined
by
default
when PC1 has sent ARP packet to all nodes to determine the link and test how it
will
reroute and
the time
it
takes to tell
the other
nodes about what
happen and
try to find a new route back.
