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
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.
