About GARP VLAN Registration Protocol (GVRP)
The
following
sections
describe
the
device
operation
when
its
ports
are
operating
under
the
Generic
Attribute
Registration
Protocol
(GARP)
application
–
GARP
VLAN
Registration
Protocol
(GVRP).
Overview
The
purpose
of
GVRP
is
to
dynamically
create
VLANs
across
a
switched
network.
When
a
VLAN
is
declared,
the
information
is
transmitted
out
GVRP
configured
ports
on
the
device
in
a
GARP
formatted
frame
using
the
GVRP
multicast
MAC
address.
A
switch
that
receives
this
frame,
examines
the
frame,
and
extracts
the
VLAN
IDs.
GVRP
then
creates
the
VLANs
and
adds
the
receiving
port
to
its
tagged
member
list
for
the
extracted
VLAN
ID
(s).
The
information
is
then
transmitted
out
the
other
GVRP
configured
ports
of
the
device.
Figure 10
‐

shows
an
example
of
how
VLAN
blue
from
end
station
A
would
be
propagated
across
a
switch
network.
How It Works
In
Figure 10
‐
1
on
page 10
‐
21,
Switch
4,
port
1
is
registered
as
being
a
member
of
VLAN
Blue
and
then
declares
this
fact
out
all
its
ports
(2
and
3)
to
Switch
1
and
Switch 2.
These
two
devices
register
this
in
the
port
egress
lists
of
the
ports
(Switch
1,
port
1
and
Switch
2,
port
1)
that
received
the
frames
with
the
information.
Switch
2,
which
is
connected
to
Switch
3
and
Switch
5
declares
the
same
information
to
those
two
devices
and
the
port
egress
list
of
each
port
is
updated
with
the
new
information,
accordingly.
Configuring
a
VLAN
on
an
802.1Q
switch
creates
a
static
VLAN
entry.
The
entry
will
always
remain
registered
and
will
not
time
out.
However,
dynamic
entries
will
time
‐
out
and
their
registrations
will
be
removed
from
the
member
list
if
the
end
station
A
is
removed.
This
ensures
that,
if
switches
are
disconnected
or
if
end
stations
are
removed,
the
registered
information
remains
accurate.
The
end
result
is
that
the
port
egress
list
of
a
port
is
updated
with
information
about
VLANs
that
reside
on
that
port,
even
if
the
actual
station
on
the
VLAN
is
several
hops
away.
