Example: Virtual Networks Using OSPF with ip ospf vnet area Command
This example differs from the prior example regarding the association between OSPF instances and a
particular interface. In this example, OSPF is running on all of the virtual networks of a trunk interface.
The ip ospf vnet area command associates the GigabitEthernet 0/0/0 interface with the three OSPF
instances.
vrf definition red
vnet tag 100
address-family ipv4
exit-address-family

vrf definition blue
vnet tag 200

Example: Overriding Command Inheritance
In the following example, the OSPF cost of 30 for VRF blue overrides the OSPF cost of 20 for the other
VRFs on the interface:
interface gigabitethernet 2/0/0
vnet trunk
ip address 10.1.1.1 255.255.255.0
! Set OSPF cost for all VRFs on this interface to 20.
ip ospf cost 20
vnet name blue
description Subinterface for VRF NG blue
! Set OSPF cost for blue to 30.
ip ospf cost 30
The show derived command indicates the subinterface changed to a cost of 30:
Device(config-if-vnet)# do show derived | s interface GigabitEthernet2/0/0
interface GigabitEthernet2/0/0
vnet trunk
