  Explanation

  Use cu-red under interfaces facing SW1 & SW3:

  On R1:

  interface Ethernet0/0 ip vrf forwarding cu-red

  ip address 192.168.1.254 255.255.255.0

  Check reachability to SW1:

  R1#ping vrf cu-red 192.168.1.1

  Type escape sequence to abort.

  Sending 5, 100-byte ICMP Echos to 192.168.2.1, timeout is 2 seconds:

  !!!!!

  Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

  On R2:

  interface Ethernet0/0 ip vrf forwarding cu-red

  ip address 192.168.2.254 255.255.255.0

  Check reachability to SW3:

  R2#ping vrf cu-red 192.168.2.1

  Type escape sequence to abort.

  Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:

  !!!!!

  Use vrf cu-green for SW2 & SW4:

  On R1:

  interface Ethernet0/1 ip vrf forwarding cu-green

  ip address 192.168.20.254 255.255.255.0

  Test reachability to SW2:

  R1#ping vrf cu-green 192.168.20.1

  Type escape sequence to abort.

  Sending 5, 100-byte ICMP Echos to 192.168.22.1, timeout is 2 seconds:

  !!!!!

  Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

  On R2:

  interface Ethernet0/1 ip vrf forwarding cu-green

  ip address 192.168.22.254 255.255.255.0

  Test reachability to SW4:

  R2#ping vrf cu-green 192.168.22.1

  Type escape sequence to abort.

  Sending 5, 100-byte ICMP Echos to 192.168.20.1, timeout is 2 seconds:

  !!!!!

  Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

  On R1:

  interface Ethernet0/2.100

  mpls ip

  !

  interface Ethernet0/2.200

  mpls ip

  !

  Configure BGP:

  router bgp 65000

  neighbor 10.10.10.2 remote-as 65000

  neighbor 10.10.20.2 remote-as 65000

  !

  address-family vpnv4

  neighbor 10.10.10.2 activate

  neighbor 10.10.20.2 activate

  exit-address-family

  !

  address-family ipv4 vrf cu-green redistribute connected

  exit-address-family

  !

  address-family ipv4 vrf cu-red redistribute connected

  exit-address-family

  !

  R1(config)#ip vrf cu-red

  R1(config-vrf)#route-target both 65000:100

  !

  R1(config)#ip vrf cu-green

  R1(config-vrf)#route-target both 65000:200

  On R2:

  interface Ethernet0/2.100

  mpls ip

  !

  interface Ethernet0/2.200

  mpls ip

  !

  router bgp 65000

  exit-address-family

  !

  address-family ipv4 vrf cu-red redistribute connected

  exit-address-family

  R2(config)#ip vrf cu-red

  R2(config-vrf)#route-target both 65000:100

  !

  R2(config)#ip vrf cu-green

  R2(config-vrf)#route-target both 65000:200

  Verification:

  From SW1 to SW3:

  SW1#ping 192.168.1.1

  Type escape sequence to abort.

  Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:

  !!!!!

  Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

  But can't Reach SW2 or SW4 in VRF cu-green:

  SW1#ping 192.168.22.1

  Type escape sequence to abort.

  Sending 5, 100-byte ICMP Echos to 192.168.22.1, timeout is 2 seconds:

  Success rate is 0 percent (0/5)

  Same Test for SW2:

  From SW2 to SW4:

  SW2#ping 192.168.20.1

  Type escape sequence to abort.

  Sending 5, 100-byte ICMP Echos to 192.168.20.1, timeout is 2 seconds:

  !!!!!

  Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

  But can't Reach SW3 or SW1 in VRF cu-red:

  SW2#ping 192.168.1.1

  Type escape sequence to abort.

  Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:

  !!!!!

  Success rate is 0 percent (0/5)

  SW2#ping 192.168.2.1

  Type escape sequence to abort.

  Sending 5, 100-byte ICMP Echos to 192.168.2.1, timeout is 2 seconds:

  !!!!!

  Success rate is 0 percent (0/5)

  Both R1 & R2 has separate tables for VRFs cu-red and cu-green.
