In some cases, it is not practical to have just one default gateway. For example, this is true in routed wireless
networks with more than two WI-MOD-xxx-E-5W routers, and in some cases when WDS router interfaces are
used. If more than one

“next-hop router” is required, the WI-MOD-xxx-E-5W allows for up to 100 routing rules to

be configured.  A routing rule specifies a destination network  (or host) IP address and the corresponding  next-hop
router that messages for the specified  destination  will be forwarded  to. It is assumed that the next-hop  router (or
gateway) will then deliver the data to the required destination (or forward  it on to  another router that  will).

Figure 51 Routing

Figure 51 illustrates a situation where routing rules may need to be configured. In this example, the WI-MOD-xxx-E-
5W

clients need only specify  the access point  as their default gateway (they require no routing  rules to be configured).
However, for the access point  to be able to deliver traffic  to LAN B and LAN C it needs to have routing  rules
configured  that specify  the respective WI-MOD-xxx-E-5W client/routers  as next-hop  routers (gateways) to
networks  B and C.

Note that  devices on LAN A should specify  the WI-MOD-xxx-E-5W access point  as their default gateway. An
alternative to adding  routing  rules to the WI-MOD-xxx-E-5W in this example would  be for each device on LAN A that
needs to communicate with  LAN B and C to have independent routing  rules specifying  the WI-MOD-xxx-E-5W
clients at B and C as gateways to those networks.

The routing  rules for the access point  in the above example are shown in Figure 52. The first entry shows the route
to LAN B. The gateway for the route to LAN B is configured  as the wireless IP address of the WI-MOD-xxx-E-5W
client connected  to LAN B. The destination for the route is configured  as the network  address of LAN B. Because
the host ID of the destination IP address is 0, it specifies a network  address. Consequently, any traffic  received at
the access point  with  destination IP address 169.254.109.x (where x is any host ID) will be forwarded  to the WI-
MOD-xxx-E-5W at LAN B.
