ip vrf Customer_A
!--- Enables the VPN routing and forwarding (VRF) routing table
!--- This command can be used in global or
!--- router configuration mode
rd 100:110
!--- Route distinguisher creates routing and forwarding
!--- tables for a VRF
route-target export 100:1000
!--- Creates lists of import and export route-target extended
!--- communities for the specified VRF
route-target import 100:1000

interface Loopback101
ip vrf forwarding Customer_A
!--- Associates a VRF instance with an interface or subinterface
ip address 200.0.4.1 255.255.255.0
!--- Loopback101 and 102 use the same IP address, 200.0.4.1.
!--- This is allowed because they belong to two
!--- different customers' VRFs
no ip directed-broadcast
