Network Router User's Manual

Billion 800VGT Router
RIP:
RIP
v1,
RIP
v2,
and
RIP
v2
Multicast.
Check
to
enable
RIP
function.
MTU:
Maximum
Transmission
Unit.
The
size
of
the
largest
datagram
(excluding
media-specific
headers)
that
IP
will
attempt
to
send
through
the
interface.
Advanced Options (PPPoA)
LLC
Header:
Selects
encapsulation
mode,
select
true
for
using
LLC
or
false
for
using
VC-Mux.
Create
Route:
This
setting
specifies
whether
a
route
is
added
to
the
system
after
IPCP
(Internet
Protocol
Control
Protocol)
negotiation
is
completed.
If
set
to
enabled,
a
route
will
be
created
which
directs
packets to
the
remote
end
of
the
PPP
link.
Specific
Route:
This
setting
specifies
whether
the
route
created
when
a
PPP
link
comes
up
is
a
specific or
default
route.
If
set
to
enabled,
the
route
created
will
only
apply
to
packets
for
the
subnet
at
the
remote end
of
the
PPP
link.
The
address
of
this
subnet
is
obtained
during
IPCP
negotiation.
Subnet
Mask:
This
sets
the
subnet
mask
used
for
the
local
IP
interface
connected
to
the
PPP
transport. If
the
value
0.0.0.0
is
supplied,
the
netmask
will
be
calculated
from
the
class
of
the
IP
address
obtained
during
IPCP
negotiation.
Route
Mask:
This
sets
the
subnet
mask
used
by
the
route
that
is
created
when
a
PPP
link
comes
up.
If
it is
set
to
0.0.0.0,
the
subnet
mask
is
determined
by
the
IP
address
of
the
remote
end
of
the
link.
The
class of
the
IP
address
is
obtained
during
IPCP
(Internet
Protocol
Control
Protocol)
negotiation.
MRU:
Maximum
Receive
Unit.
This
is
negotiated
during
the
LCP
protocol
stage.
Discover
Primary
/
Secondary
DNS:
This
setting
enables/disables
whether
the
primary/secondary
DNS
server
address
is
requested
from
a
remote
PPP
peer
using
IPCP.
The
default
setting
for
this
command
is
enabled.
Give
DNS
to
Relay:
This
controls
whether
the
PPP
Internet
Protocol
Control
Protocol
(IPCP)
can
request
the
DNS
server
IP
address
for
a
remote
PPP
peer.
Once
IPCP
has
discovered
the
DNS
server
IP
address,
it
automatically
gives
the
address
to
the
local
DNS
relay
so
that
a
connection
can
be
established.
Give
DNS
to
Client:
Controls
whether
the
PPP
Internet
Protocol
Control
Protocol
(IPCP)
can
request
a
DNS
server
IP
address
for
a
remote
PPP
peer.
Once
IPCP
has
discovered
the
DNS
server
IP
address,
it
automatically
gives
the
address
to
the
local
DNS
client
so
that
a
connection
can
be
established.
Give
DNS
to
DHCP
Server:
Similar
to
the
above,
but
gives
the
DNS
server
address
to
the
DHCP
server.
Discover
Primary
NBNS
/
Discover
Secondary
NBNS:
This
setting
enables/disables
whether
the
primary/secondary
NBNS
server
address
is
requested
from
a
remote
PPP
peer
using
IPCP.
The
default
setting
for
this
command
is
disabled.
Discover
Subnet
Mask:
This
specifies
if
the
subnet
mask
given
by
IPCP
negotiation
process
is
to
be
used.
Give
Subnet
Mask
To
DHCP
Server:
Enable
to
change
your
DHCP
Server
settings
by
using
the
given
information
in
IPCP
negotiation
process.
