extension of the original Routing Information Protocol (RIP-1) that expands the amount of useful infor-
mation in the RIP packets. While RIP-1 and RIP-2 share the same basic algorithms, RIP-2 suppor ts sev-
eral additional features, including inclusion of subnet masks in RIP packets and implementation of
multicasting instead of broadcasting (which reduces the load on hosts which do not suppor t routing
protocols. RIP-2 with MD5 authentication is an extension of RIP-2 that increases security by requiring
an authentication key when routes are adver tised.
If you specify
v2-MD5
, you must also specify a
rip-send-key
. Keys are ASCII strings with a maximum of
31 characters, and must match the other Gateway(s) keys for proper operation of MD5 suppor t.
Depending on your network needs, you can configure your Motorola Netopia® Gateway to suppor t RIP-
1, RIP-2, or RIP-2MD5.
set ip ethernet A rip-receive { off | v1 | v2 | v1-compat | v2-MD5 }
Specifies whether the Motorola Netopia® Gateway should use Routing Information Protocol (RIP) broad-
casts to update its routing tables with information received from other Gateways on your network.
If you specify
v2-MD5
, you must also specify a
rip-receive-key
. Keys are ASCII strings with a maximum
of 31 characters, and must match the other Gateway(s) keys for proper operation of MD5 suppor t.
Additional subnets
See
“DHCP Settings” on page 149
for subnet range configuration commands.
set ip ethernet A subnet [ 2 ... 8 ] option [ on | off ]
Enables or disables additional LAN subnets. Up to seven additional subnets may be configured.
set ip ethernet A subnet
n
address
ip_address
Specifies an IP address for the subnet
n
, when
subnet
n
option
is
on
.
set ip ethernet A subnet
n
netmask
netmask
Specifies the subnet mask for the subnet
n
, when
subnet
n
option
is
on
.
Default IP Gateway Settings
set ip gateway option [ on | off ]
Specifies whether the Motorola Netopia® Gateway should send packets to a default Gateway if it does
not know how to reach the destination host.
set ip gateway interface [
ip_address
|
ppp_vccn
]
Specifies how the Motorola Netopia
®
Gateway should route information to the default Gateway. If you
select
ip_address
, you must enter the IP address of a host on a local or remote network. If you specify
ppp
, the Motorola Netopia
®
unit uses the default gateway being used by the remote PPP peer.
