Enabling IP Routing

Configuring an IP
Network over the LAN
To configure IP routing, IP must be defined on both the LAN interface and one or
more VC profiles. On the LAN, an IP network must exist with a specified IP address
and subnet mask. In the VC profile, IP routing needs to be enabled, and the
remote router address, a remote subnet mask and local WAN interface address
need to be configured. The remote site address configuration can be learned
dynamically when the connection is established if the Network Service is PPP,
otherwise it has to be specified.
Remember to save your configuration using the save all command before
rebooting your OfficeConnect Remote 812 so that your changes will be written to
permanent FLASH memory.
When the OfficeConnect Remote 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 OfficeConnect Remote 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.
