Configuring VRF
Typical full-blown implementations of VRFs are designed to support BGP/MPLS VPNs, whereas
VRF-lite implementations typically are much simpler with moderate scalability (as compared to
BGP/MPLS VPNs). These two flavors share a lot in common but differ in the interconnect schemes,
routing protocols used over the interconnect, and also in the VRF classification mechanisms.
Brocade Network OS v4.1.1 supports the VRF-lite implementation. All references to VRF in this
document implicitly indicate VRF-lite.
Figure 10 shows a typical single VCS comprising Customer
Edge 1, Provider Edge, and Customer Edge 2 routers.
FIGURE 10 VRF configuration diagram
ORANGE (v11) and GREEN (v12) are the two VPNs supporting two different customer sites. Both of
them have overlapping IP subnets; 100.100.100.0/24 and 100.100.200.0/24.
VRF is supported on the Brocade VDX 8770 and VDX 6740, supporting up to 32 VRFs.
This configuration gives an example of a typical VRF-lite use case and is not meant to give an ideal
configuration.
The examples in this section are based on the network diagram in Figure 10 .
1. Configure the edge routers by enabling OSPF protocol in VRF configuration mode.
Example of enabling routing and configuring VRF on the ORANGE edge router. Repeat this
example for the GREEN edge router.
