3. (Optional) Congure the VRF to ensure that essential OSPF neighbor state changes are logged, especially in the case of errors.
device(config-ospf-router-vrf-corporate)# log adjacency
Assigning a Layer 3 interface to a VRF
The following example illustrates how a virtual Ethernet (VE) interface is assigned to a VRF, and how IP addresses and the OSPF
protocol are congured.
ATTENTION
After you congure a VRF instance on the device, you must assign one or more Layer 3 interfaces (physical or virtual Ethernet)
to the VRF. When you do this, all existing IP addresses are deleted; this action also triggers cache deletion, route deletion, and
associated cleanup. After you assign an interface to the VRF, you must recongure the IP address and interface properties.
1. Enter global conguration mode.
device# configure terminal
2. In global conguration mode, enter the interface ve command to create a VE interface.
device(config)# interface ve 10
3. In VE conguration mode, enable forwarding for the VRF "guest".
device(config-vif-10)# vrf forwarding guest
Warning: All IPv4 and IPv6 addresses (including link-local) on this interface have been removed
have been removed
4.
Congure an IPv4 address and mask on the VE interface.
device(config-vif-10)# ip address 192.168.1.254/24
5. Enable OSPF Area 0.
device(config-vif-10)# ip ospf area 0
6.
Congure the interface as passive.
device(config-vif-10)# ip ospf passive
device(config-vif-10)# exit
7. Exit the conguration.
device(config-vif-10)# exit
