Configuring Routers

Configuring Routers

Follow the procedure in this chapter to configure a router on the BBSM internal network. (Refer to your network configuration information to configure the router fields.)

In BBSM, all network devices are associated with a router. This association tells BBSM how to build routes to the network internal to the router. For additional information about networking options, including routed networks, refer to the "Transmission and Networking Options" section.

Note In a bridged BBSM internal network, all network devices are associated with router 0, the BBSM server. If your internal network is bridged, you do not need to configure a router on BBSM.

Step 1 From the Dashboard, click WEBconfig. The BBSM Server Settings web page appears.

Step 2 In the NavBar, click Routers. The Routers web page appears. (Figure 9-1 shows the Routers web page for a multinet, dual-VLAN configuration.)

Step 3 Enter the router data based on the information shown in Table 9-1 and click Save. (For router number 0, which is the BBSM server, all fields except Router Number and SNMP Password are disabled. These fields are enabled only if the router number is greater than 0.)

Table 9-1 Routers Web Page Options 


Router Number

Displays the router number of the router being configured. (BBSM degenerates this number.) Click Go to advance to the router number entered in the text field to the left of the Go button. Use this field to conveniently retrieve any router record without having to use the > or < buttons to advance through each router.

Gateway to Router

Enter the IP address of the first hop from the BBSM server to the router. This address should be on the BBSM server's internal network and is the router's external address if the router is connected directly to the BBSM server's network.

Router IP Address

Displays the client-side IP address of the router. On clients, this IP address is the default gateway. For clients connected to the BBSM server internal network, the gateway is the BBSM server's internal NIC address. The default is (This loopback IP address refers to the BBSM server and cannot be changed for router 0.)

Client Start
Client End
Client Subnet Mask

Enter the starting and ending IP addresses and the subnet mask for the clients connecting to this router. This subnet mask value must be configured on the clients and is set automatically for DHCP clients.

Temp DHCP Start
Temp DHCP End

(multinet only)

Enter the starting and ending IP addresses for the temporary DHCP address range.

Router Dual VLAN Support

Check this check box to enable dual VLANs on the router. This feature is disabled by default.

Mgmt Router IP
Mgmt Start
Mgmt End
Mgmt Subnet Mask

Note These fields apply only when two VLANs are configured.

Enter the IP address of the router for the management VLAN and the starting and ending IP address and subnet mask of the network devices in the management VLAN.

Router Supports SNMP

If you are using a router that supports SNMP, check this check box:

For router 0 (the BBSM server), the check box is checked and disabled. The SNMP password field is enabled.

For routers other than router 0, the field is enabled. If you check the check box, the SNMP password field is enabled. Otherwise, the SNMP password is disabled.

Caution Restrictions exist to disabling Router Supports SNMP. Because BBSM does not know the client's MAC address, it cannot use a network device (switch DLL) to determine if the session is still active (the administrator must configure the null switch). This inability to identify the client affects many BBSM operations, including reporting, the Daily access policy Welcome Back feature, and any per-port policy.

SNMP Password

Enter the SNMP read-write community string (password) that is used when communicating with routers. The default is public.

Create Client DHCP Scope

Check this check box if BBSM is your DHCP server. A DHCP scope is created on the BBSM server for the router subnet, as determined by the IP addresses in the Client Start and Client End fields.

Leave the check box unchecked if you are using a DHCP server other than BBSM.

Multiple VLANs

(dual VLANs only)

Clients VLAN ID

Displays the client VLAN ID.


Displays the management VLAN ID.
