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
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.
