28 Converged small site (mixed-vendor environment): reference topology 1

In this example, two port-based VLANs are established on the BES100/200.

VLAN 1 is the default VLAN with a port membership of 1 through 10 and 12

through 50, leaving port 11 out of the VLAN. VLAN 2 is also a port-based

VLAN with port membership of 1, 2, and 11. VLAN 2 allows ports 1 and 2 to

be members of the guest and default management VLANs, but keeps port

11 separated as a wired port dedicated to the guest VLAN only.

This reference topology descr ibes a simple example; however, port selection

for VLANs must reﬂect the speciﬁc needs of the installation.

Installing and conﬁguring the third-party router

Step Action

Install the third-party router, referring to the manufacturer’s

documentation and procedures.

Set the following parameters on the third-party router:

a. support of network address translation (NAT)

b. support of the static routing function

c. support of four at a minimum, but preferably eight LAN-based

routings for each physical port

d. support of VPN gateway static and dynamic tunnels (IPSec data

encryption standard (DES) and 3DES encryption)

e. support of multiscope DHCP server function: four subnets at a

minimum, but preferably eight

f. support of Stateful ﬁrewall functions

3 Conﬁgure the NAT IP address translation by using the many-to-one

port-based method.

ATTENTION

For the Voice VLAN, two DHCP servers exist: one on the third-party

router and one on the BCM50. You must conﬁgure the IP address pools

for each of these DHCP servers so that IP addresses for the third-party

router are not duplicated in the BCM50 IP address range and vice versa.

Conﬁgure the third-party router DHCP server with mapping of subnet

to VLAN-tagged trafﬁc as follows:

a. DHCP server pool-1 = 192.168.1.2 to 192.168.1.127, mask

255.255.255.0, default gateway 192.168.1.1

b. DHCP server pool-2 = 192.168.2.2 to 192.168.2.127, mask

255.255.255.0, default gateway 192.168.2.1
