OSPF over VRF

OSPF over VRF
With Network OS 4.0 and later, OSPF can run over multiple Virtual Forwarding and Routing (VRF)
mechanisms. OSPF maintains multiple instances of the routing protocol to exchange route
information among various VRFs. A multi-VRF-capable router maps an input interface to a unique
VRF, based on user configuration. These input interfaces can be physical or SVIs. By default, all
input interfaces are attached to the default VRF. All OSPF commands supported in Network OS 4.0
and later are available over default and non-default OSPF instances.
NOTE
For more information about OSPF over VRF, refer to Chapter 36, “Configuring VRF” .
OSPF in a VCS environment
Figure 6 shows one way in which OSPF can be used in a VCS Fabric cluster environment. Routers
RB1 and RB2, as well as the MLX switches, are configured with OSPF. Switches RB3, RB4, and RB5
are Layer 2 switches.
FIGURE 6 OSPF example in a VCS environment
1. On Router RB1, issue an RPC to perform the following tasks:
a. Configure a VLAN for the router.
b. Enable OSPF for the RB1.
c. Create an OSPF area on RB1.
d. Configure a virtual Ethernet (VE) interface using the VLAN number created in step a .
e. Configure an IP address for the VE interface.
