2. Assign the interface to management VRF.
INTERFACE CONFIGURATION
ip vrf forwarding management
Before assigning a front-end port to a management VRF, ensure that no IP address is configured on the interface.
3. Assign an IPv4 address to the interface.
INTERFACE CONFIGURATION
ip address 10.1.1.1/24
Before assigning a front-end port to a management VRF, ensure that no IP address is configured on the interface.
4. Assign an IPv6 address to the interface.
INTERFACE CONFIGURATION
ipv6 address 1::1
You can also auto configure an IPv6 address using the ipv6 address autoconfig command.
View VRF Instance Information
To display information about VRF configuration, enter the show ip vrf command. To display information on all VRF instances
(including the default VRF 0), do not enter a value for vrf-name.
● Display the interfaces assigned to a VRF instance.
EXEC
show ip vrf [vrf-name]
Assigning an OSPF Process to a VRF Instance
OSPF routes are supported on all VRF instances. See the Open Shortest Path First (OSPFv2) chapter for complete OSPF
configuration information.
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.
Once the OSPF process and the VRF are tied together, the OSPF Process ID cannot be used again in the system.
● 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.
CONFIGURATION
router ospf process-id vrf vrf name
The process-id range is from 0-65535.
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. .
