Below is the task required from INE Vol1 MPLS workbook the main aim was to establish Inter-Vrf routing without using MPLS ( well i used a BGP solution) which differs from the solution offered in INE book
My idea was to test how can i exchange inter-vrf routing using BGP , INE made a tricky solution which is configuring R6 to exhange routes statically

ip route vrf VPN_A 192.168.7.0 255.255.255.0 FastEthernet0/0.76 155.1.76.7
!
ip route vrf VPN_B 172.16.7.0 255.255.255.0 FastEthernet0/0.67 155.1.67.7


Note This trick only works if their is no recursive routing needed (i.e) next hop appears as connected

So here's below my Solution without the need to R6 and only using BGP vpnv4
  ip vrf VA
  route-target export 1:1
  route-target import 2:2
  ip vrf VB
  route-target export 2:2
  route-target import 1:1
  router bgp 1
  address-family ipv4 vrf VB
  redis connected route-map match-lo102
  address-family ipv4 vrf VA
  redis connected route-map match-lo101
route-map match-lo101
match interface lo101
route-map match-lo102
match interface lo102

Rack1SW1#sh ip route vrf VA bgp
     192.168.7.0/32 is subnetted, 1 subnets
B       192.168.7.7 is directly connected, 00:00:29, Loopback102
Rack1SW1#sh ip route vrf VB bgp
     172.16.0.0/32 is subnetted, 1 subnets
B       172.16.7.7 is directly connected, 00:00:35, Loopback101



Rack1SW1#ping vrf VA 192.168.7.7 source 172.16.7.7

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.7.7, timeout is 2 seconds:
Packet sent with a source address of 172.16.7.7
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
