Chapter 4 FCIP over IP/MPLS Core

Testing Scenarios and Results

VRF Configuration—PE2

The following are the VRF definitions on the PE2(7500-106) router:

ip vrf storage rd 105:106

route-target export 105:106 route-target import 105:106

This test assumes the Cisco MDS 9216/9216i as the CPE. MPLS VPN VRFs allow the SPs to leverage a common backbone to offer shared transport services. To facilitate these services, the provider gets the added security mechanisms of VRFs. The VPN VRFs provide an address space separation; therefore, the use of VRFs on the PE devices and MP-BGP between them achieves address separation not only among the different VPNs but also with the SP core network. Thus Customer 1 cannot see any boxes or interfaces of Customer 2, even though they are on the same transport network and may also share the same PE device.

There is no visibility of the core network to the end storage customer, which means that the core network infrastructure including addressing and topology is not visible to the VPN customers. Customer VPN routes that originate from other PE routers across the core network are associated with the BGP next-hop address of the originating PE router. The BGP next-hop address of the PE router is not visible or reachable in the customer address space.

The use of the traceroute command can potentially reveal the addresses in the core topology. The core network address can be hidden from view in a VPN by configuring the no mpls ip propagate-ttl forwarded command. Therefore, the storage customer can be stopped from seeing the routers in the core network that are carrying the storage traffic.

Scenario 1—MDS 9216i Connection to GSR MPLS Core

In this scenario, GSR is assumed to be the provider (P) and PE device (see Figure 4-11). FCIP traffic is passed across the MPLS network. Tests were performed with different packet sizes. The MPLS networks with proper configurations of MTU size and the TCP parameters on the CPE were able to carry line rate traffic.
