Assign an IPv4 address to the interface.
NOTE: You can assign either an
IPv4 or an IPv6 address but not
both.
ip address 10.1.1.1/24
INTERFACE CONFIGURATION
Assign an IPv6 address to the interface.
NOTE: You can also auto
configure an IPv6 address using
the ipv6 address autoconfig
command.
ipv6 address 1::1

View VRF Instance Information
To display information about VRF configuration, enter the show ip vrf command.
Task Command Syntax Command Mode
Display the interfaces assigned to a VRF
instance. To display information on all
VRF instances (including the default VRF
0), do not enter a value for vrf-name.

Assigning an OSPF Process to a VRF Instance
OSPF routes are supported on all VRF instances. Refer to 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.
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.

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. .
