Dynamic
Routing
Dynamic
Routing
allows
the
ADSL
Router
to
automatically
adjust
to
physical
changes
in
the
network.
The
ADSL
Router,
using
the
RIP
protocol,
determines
the
network
packets’
route
based
on
the
fewest
number
of
hops
between
the
source
and
the
destination.
The
RIP
protocol
regularly
broadcasts
routing
information
to
other
ADSL
Routers
on
the
network.
The
Direction
determines
the
direction
that
RIP
routes
will
be
updated.
Selecting
In
means
that
the
ADSL
Router
will
only
incorporate
received
RIP
information.
Selecting
Out
means
that
the
ADSL
Router
will
only
send
out
RIP
information.
Selecting
both
means
that
the
ADSL
Router
will
incorporate
received
RIP
information
and
send
out
updated
RIP
information.
The
protocol
is
dependent
upon
the
entire
network.
Most
networks
support
Rip
v1.
If
RIP
v1
is
selected,
routing
data
will
be
sent
in
RIP
v1
format.
If
Rip
V2
is
selected,
routing
data
will
be
sent
in
RIP
v2
format
using
subnet
broadcasting.
If
Rip
V1
Compatible
is
selected,
routing
data
will
be
sent
in
RIP
v2
format
using
multicasting.
