802.11a/g Router User’s Guide
IP Routing Settings
Dynamic Routing: Enable gateway to exchange the routing table dynamically with other routing
devices. Currently you can select either RIP or OSPF as the routing protocol.
RIP: When RIP is selected, you can choose to run RIP1 or RIP2 with active mode (Send/Receive)
or passive mode (Receive Only). With active mode, the 802.11a/g Router will send out RIP
packets describing its routing database, and it will also update the database according to the
received RIP packets from other routing devices. With passive mode, the 802.11a/g Router will
only update the database according to the RIP packets received, it will not send out any RIP
packets.
OSPF: When OSPF is selected. You can select the interface (LAN and/or WAN) to run OSPF.
For each interface where OSPF is enabled, you have to configure the Area that the interface
belongs to by specifying the Area ID, the Area type (either Regular or Stub), and the priority of
the 802.11a/g Router on the segment the interface belongs to. Also, for the segment that an
OSPF enabled interface, you have to configure the Hello interval and Dead interval on the
segment, the Cost for transmitting a packet on the segment, and the Authentication method
used on the segment. If an authentication method is used, either Simple Password or MD5, a
shared secret has to be configured for the authentication purpose.
OSPF Summarization can be enabled to consolidate multiple routes into one single
advertisement and hence reduce the routing database make routing simpler and faster. When this
function is enabled, it will only be effective when the 802.11a/g Router is an ABR (Area Border
Rouer), that is, at least two OSPF enabled interface are configured with different Area IDs.
For each summarization entry, you have to enter the Area ID such that routes from the Area
falling into the specified subnet (IP address/Netmask) will be summarized into a single route to
the specified subnet and it is the single route instead of the individual route to be injected into
other Areas.
Static Routing: If you have routers on your LAN or WAN, you can configure static routes on the
802.11a/g Router to route network traffic to a specific, predefined destination. The 802.11a/g
Router routes packets based only on the packet's destination not on the source of a packet. Static
routes must be defined if the LAN or WAN are segmented into subnets. For example, a subnet
can be created to isolate a section of a company, such as finance, from traffic on the rest of the
LAN or WAN.
Static Routes are configured when network traffic is directed to a specific destination on the
network whether it is the LAN or WAN. For instance, you can configure the 802.11a/g Router
to route traffic destined to a particular network to a specific router on the LAN or WAN using
the following steps:
1. Enter the IP address of the destination network in the Destination Network field.
2. Enter the subnet in the Subnet Mask field.
3. Enter the IP address of the specific router in the Gateway IP Address field.
4. Select LAN or WAN, where is the specific router is, from the Interface menu.
