Given the following partial configuration on router R1: ```
interface GigabitEthernet0/0 ip vrf forwarding CUSTOMER_A ip address 192.168.1.1 255.255.255.0
``` What is the effect of this configuration?
Consider this partial configuration: ```
ip vrf CUSTOMER_B
rd 65000:1 route-target export 65000:1 route-target import 65000:1 ``` What statement is true about this VRF configuration?
Examine the following configuration: ```
interface GigabitEthernet0/1 ip vrf forwarding CUSTOMER_C ip address 10.1.1.1 255.255.255.0 no shutdown
``` What is missing from this configuration to ensure that routes from VRF CUSTOMER_C are properly isolated?
Given this configuration on router R2: ```
ip vrf CUSTOMER_D
rd 100:1 !
interface GigabitEthernet0/0 ip vrf forwarding CUSTOMER_D ip address 192.168.2.1 255.255.255.0
!
router ospf 1 vrf CUSTOMER_D network 192.168.2.0 0.0.0.255 area 0
``` What will happen when this configuration is applied?
Consider the following configuration: ```
ip vrf CUSTOMER_E
rd 200:1 route-target export 200:1 route-target import 200:1 !
interface GigabitEthernet0/0 ip vrf forwarding CUSTOMER_E ip address 172.16.0.1 255.255.255.0
!
interface GigabitEthernet0/1 ip vrf forwarding CUSTOMER_E ip address 172.16.1.1 255.255.255.0
``` What is the effect of the route-target commands in this VRF-Lite scenario?
Examine this partial configuration: ```
interface GigabitEthernet0/0 ip vrf forwarding CUSTOMER_F ip address 10.10.10.1 255.255.255.0
!
interface GigabitEthernet0/1 ip vrf forwarding CUSTOMER_G ip address 10.10.20.1 255.255.255.0
``` What is required to enable communication between VRF CUSTOMER_F and VRF CUSTOMER_G?
