Address-family ipv4 vrf vpnxx does not appear under BGP on GNS3

Hi Experts

I have got a problem that Im getting on GNS3 and not sure if anyone has
encountered the same problem .

Below is the setup

Rx(mpls/isis/mpbgp)-----------------Ry(mpls/isis)--------------------------Rz(mpls/isis/mpbgp))

When I create a VRF instance under BGP on either Rx/Rz ,that vrf does not
appear under BGP until I use redistribute connected. Once the
 address-family ipv4 vrf vpnxx
appears in BGP,Im unable to exchange VPNv4 routes between Rx and Rz. I
 tried to use BGP/EIGRP as the PE-CE routing protocol but still getting
the same results.

Rx(config-router)#router bgp 200
Rx(config-router)#address-family ipv4 vrf vpnb

Rx#sh run | sec router bgp
router bgp 200
 no synchronization
 bgp router-id 19.19.19.19
 bgp log-neighbor-changes
 neighbor 20.20.20.20 remote-as 200
 neighbor 20.20.20.20 update-source Loopback0
 no auto-summary
 !
 address-family vpnv4
  neighbor 20.20.20.20 activate
  neighbor 20.20.20.20 send-community both
 exit-address-family
 !
 address-family ipv4 vrf vpna
  no synchronization
  redistribute rip
 exit-address-family

now let me try redistribute connected under the vrf and you will notice
the address-family appears now in the config.

Rx(config)#router bgp 200
Rx(config-router)#address-family ipv4 vrf vpnb
Rx(config-router-af)#redistribute connected

Rx#sh run | sec router bgp
router bgp 200
 no synchronization
 bgp router-id 19.19.19.19
 bgp log-neighbor-changes
 neighbor 20.20.20.20 remote-as 200
 neighbor 20.20.20.20 update-source Loopback0
 no auto-summary
 !
 address-family vpnv4
  neighbor 20.20.20.20 activate
  neighbor 20.20.20.20 send-community both
 exit-address-family
 !
 address-family ipv4 vrf vpna
  no synchronization
  redistribute rip
 exit-address-family
 !
 address-family ipv4 vrf vpnb
  no synchronization
  redistribute connected
 exit-address-family
Rx#

Now let me check for VPNv4 routes under Rx because these routes are
already available on Rz

Rz#sh ip bgp vpnv4 all
BGP table version is 25, local router ID is 20.20.20.20

Rz#

VPNv4 routes appear on Rz but nothing on Ry

Rx#sh ip bgp vpnv4 all
