QuestionQ164

Layer 3 Technologies

An engineer is carrying out a coordinated change with a server team. As part of this change, the engineer must configure interface GigabitEthernet2 in the existing VRF "RED" and later move the interface to the existing VRF "BLUE" when the server team is ready. The engineer configured GigabitEthernet2 in VRF "RED":

interface GigabitEthernet2  
description Migration ID: B410A82D0935G35  
vrf forwarding RED  
ip address 10.0.0.0 255.255.255.254  
negotiation auto

Which configuration completes the change?

  • A interface GigabitEthernet2 no vrf forwarding RED vrf forwarding BLUE ip address 10.0.0.0 255.255.255.254
  • B interface GigabitEthernet2 no ip address vrf forwarding BLUE
  • C interface GigabitEthernet2 no vrf forwarding RED vrf forwarding BLUE
  • D interface GigabitEthernet2 no ip address ip address 10.0.0.0 255.255.255.254 vrf forwarding BLUE
Explanation

A VRF association is removed with no vrf forwarding RED before the interface is associated with VRF BLUE. Configuring vrf forwarding BLUE removes the interface’s existing IP address, so 10.0.0.0 255.255.255.254 must be reapplied after the new VRF association.
