Active Routing
To configure a PortServer II port for active routing, proceed as follows:
1. Configure a WAN connection, as described in Chapter 8, Configuring WAN
Connections.
2. If static routes are needed beyond those contained in the WAN connection, con-
figure each route by entering a command in the format:
set route net=<network_address> mask=<ipmask>
gateway=<ip_address> metric=<numhops>
<network_address>
is the address of the network or host that PortServer II
will route IP packets to.
<ipmask>
is the subnet mask, if used, or
255.255.255.255
if you are configuring a route to a single host.
<ipaddress>
is the IP address of the gateway that IP packets covered by this
routing entry should be forwarded to.
<numhops>
is the number of hops
(gateways) between PortServer II’s network and the final destination.
For example,
set route net=192.83.159.2 mask=255.255.255.128
gateway=192.83.160.1 metric=3
3. Set forwarding to active, by entering the following command:
set forwarding state=active [proxyarp=<state>]
<state>
should be
on
if you are using the Proxy ARP, otherwise
off
.
For example:
set forwarding state=active advertise=30 timeout=180
Note:
set forwarding
allows you to set ICMP Router Discovery packet
parameters. For information on this and other
set forwarding
options, refer to the Command Reference Guide.
4. Check that the Route Table is displayed and that new routes are added periodi-
cally as they are received from other routers.
