Assign an OSPF process to a VRF instance . Return to CONFIGURATION mode to enable the OSPF process. The OSPF Process ID is the
identifying number assigned to the OSPF process, and the Router ID is the IP address associated with the OSPF process.
Table 86. Assigning an OSPF Process to a VRF Instance
Task Command Syntax Command Mode
Enable the OSPFv2 process globally for a
VRF instance. Enter the VRF key word and
instance name to tie the OSPF instance to
the VRF. All network commands under this
OSPF instance are subsequently tied to the
VRF instance. process-id range: 0-65535

name
CONFIGURATION
Once the OSPF process and the VRF are tied together, the OSPF Process ID cannot be used again in the system.
Configuring VRRP on a VRF Instance
You can configure the VRRP feature on interfaces that belong to a VRF instance.
In a virtualized network that consists of multiple VRFs, various overlay networks can exist on a shared physical infrastructure. Nodes
(hosts and servers) that are part of the VRFs can be configured with IP static routes for reaching specific destinations through a given
gateway in a VRF. VRRP provides high availability and protection for next-hop static routes by eliminating a single point of failure in the
default static routed network. .
