Netopia 2200 manual Set ip ethernet a netmask netmask, 253

CONFIG Commands

set ip ethernet A netmask netmask

Specifies the subnet mask for the local Ethernet interface. The subnet mask specifies which bits of the 32-bit binary IP address represent network information. The default sub- net mask for most networks is 255.255.255.0 (Class C subnet mask).

set ip ethernet A restrictions { none admin-disabled }

Specifies whether an administrator can open a telnet connection to a Netopia Gateway over an Ethernet interface (A = the LAN; B = the WAN, in the case of Ethernet WAN mod- els) to monitor and configure the unit.

The admin-disabledargument prevents access to the device via telnet, web, and SNMP.

By default, administrative restrictions are none on the LAN, but admin-disabledis set on the WAN. This means that, by default, an administrator can open, for example, a telnet connection from the LAN, but not the WAN.

set ip ethernet A rip-send

{ off v1 v2 v1-compat v2-MD5 }

Specifies whether the Netopia Gateway should use Routing Information Protocol (RIP) broadcasts to advertise its routing tables to other routers on your network. RIP Version 2 (RIP-2) is an extension of the original Routing Information Protocol (RIP-1) that expands the amount of useful information in the RIP packets. While RIP-1 and RIP-2 share the same basic algorithms, RIP-2 supports several 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 support routing protocols. RIP-2 with MD5 authen- tication is an extension of RIP-2 that increases security by requiring an authentication key when routes are advertised.

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 router(s) keys for proper operation of MD5 support.

Depending on your network needs, you can configure your Netopia Gateway to support RIP- 1, RIP-2, or RIP-2MD5.
