Scenario 3—Cisco MDS 9216i Connection to Cisco 7500 (PE)/GSR (P)

In this scenario, the Cisco 7500 is used as a PE and the FCIP traffic is passed over the GSR (P) routers (see Figure 4-15). Typically, the Cisco 7500 is used as a PE router where traffic demand is minimal. The Cisco 7500 cannot transport line rate for Gigabit Ethernet traffic and is limited to around 35 percent of Gigabit Ethernet bandwidth. This is ideal when the customer traffic is compressed and the requirement does not go beyond the capabilities of the Cisco 7500. As the traffic demand increases, the Cisco 7500 can be replaced by high performing routers like the GSR.
