Appendix B:
Overview
You can deploy BSAPs on a routed network with Layer-3 connectivity to the BSC as shown
in the following figure.
In this deployment scenario, you must ensure that each BSAP is able to communicate with
the BSC across the routed network by verifying that:
•
there are no NAT devices between the BSAPs and the BSC
•
Protocol 97 and TCP/UDP Port 3333 traffic is allowed between BSAPs and the BSC
Each BSAP will receive its IP address from your existing network DHCP server.
The BSAP also needs the IP address of the home BSC to which it will connect and from
which it will obtain its software image and configuration. You can provide the home BSC
IP address to a BSAP by manually configuring the DHCP server on your network to send
BSC IP addresses to BSAPs using DHCP vendor-specific option 43.
In DHCP requests sent from the BSAP, the BSAP uses option 60 Vendor class identifier
with a value of BlueSecure.AP1500 to identify itself to the DHCP server.
The following sections provide examples of how you may configure vendor-specific
option 43 on the following DHCP servers:
•
Provisioning a Microsoft DHCP Server
•
Provisioning an Internet Systems Consortium (ISC) DHCP Server
Provisioning a Microsoft DHCP Server
To provision a Microsoft DHCP Server to pass the IP address of one or more BSCs to a
BSAP using DHCP Option 43 (Vendor Specific Information), you must complete these
three steps:
Define the Vendor Class.
1.
Set a value for predefined option 43.
2.
3.
Configure the Option for the BSAP DHCP address scope.
Define the
Define the vendor class by making the DHCP server aware of the vendor class

1.
Access the Microsoft DHCP server management window, right click on the DHCP
server in the navigation tree, and select Define Vendor Classes... For example:
