Enabling Ip Routing; Configuring An Ip Network Over The Lan - 3Com OfficeConnect Remote 812 Cli User's Manual

Enabling IP Routing

Configuring an IP
Network over the LAN
When the OCR 812 is to be used for IP Routing, IP forwarding must be enabled.
This is a global setting for the entire router.
To enable IP routing, use the command:


enable ip forwarding
To disable IP routing, use the command:


disable ip forwarding
IP Forwarding refers to the routing of IP packets from one interface to another. It
does not affect communicating to the OCR 812 itself. Even when IP Forwarding is
disabled, you can perform non-routing functions such as use a Web browser to
manage the unit and use PING.
In addition to IP forwarding, there is a global RIP setting. If RIP is globally disabled,
it is disabled for all LAN and WAN networks. If RIP is globally enabled, it can then
be specifically enabled or disabled on the LAN IP networks and in each remote
site's VC profile.
To globally enable IP RIP, use the command:


enable ip RIP
To globally disable IP RIP, use the command:


disable ip RIP
To see the current IP Forwarding and RIP status, use the following commands:


show ip settings
show ip routing settings
To configure IP over the LAN, you need to assign an IP network to the LAN port
with the add ip network command. Each network has a network name. You will
use the network name when entering commands related to the network.
The CIDR-supported network address includes a local station address and subnet
mask using the format: nnn.nnn.nnn.nnn/A B C or 8-30. The first 4 octets describe
the IP address, followed by the subnet mask (contiguous) designator.
You can specify the subnet in one of two ways: a class or numerical designation.
If you specify a Class C subnet mask, for instance, this command will generate a
255.255.255.0 subnet value for you. If you specify the number of bits (to be set
to 1), the acceptable range is 8-30. The network address is invalid if the portion of
the station address not covered by the mask is 0.
Defining a numerical subnet is useful when your value falls in between classes.
You can also omit the mask altogether; it will automatically be calculated from the
address.
To add an IP network over the LAN, use the command:


add ip network <network name>
address <ip address/mask>
