Network Configuration Example
Using Allied Telesyn’s Gigabit Ethernet switches, you can build a
complete end-to-end LAN switching infrastructure that consistently
delivers the same functionality, features, and management interface
throughout. Functionality includes non-blocking switch fabric, wire-
speed routing, and Policy-Based QoS. Features include IP routing
with RIP, RIP v2, and OSPF, IP multicast routing support with IGMP,
DVMRP, and PIM-DM, VLAN support by way of IEEE 802.1Q (including
the Generic VLAN Registration Protocol, or GVRP), and standard
packet prioritization using IEEE 802.1p (also known as IEEE 802.1D-
1998).
The switches deliver the maximum price performance in a small, 3.5
inch-high package. The needs of smaller networks can be satisfied
with AT-8525 and AT-8550 Enterprise desktop switches aggregated
by other Allied Telesyn switches.
In most networks, desktop switches at the edge of the network are
aggregated with core and segment switches. An example of this
configuration is illustrated in Figure 1-1.
