Inter-AS MPLS VPN

Hello Experts,

In Option 3 (10C): Multi-Hop MP-eBGP Between RR and eBGP Between ASBRs -
Inter-AS MPLS VPN, the routes are not learned by ASBR. This is an expected
behavior. But I could not understand the reason.

In my scenario R2 is the PE which redistribute the route 200.0.0.4/32 into
VPNV4 table, R1 is the RR which receives VPNV4 route from R2 and R5 is ASBR
connected to other AS which is not receiving the route from RR. Though it is
an expected behavior, Could someone explain the reason.

R2#sh ip bgp vpnv4 all | inc 200.0.0.4
*> 200.0.0.4/32 150.50.24.1 1 32768

R2#sh ip bgp vpnv4 all labels | inc 200.0.0.4
   200.0.0.4/32 150.50.24.1 19/nolabel

R1#sh ip bgp vpnv4 all | inc 200.0.0.4
*>i200.0.0.4/32 200.0.0.2 1 100 0 ?

R1#sh ip bgp vpnv4 all labels | inc 200.0.0.4
   200.0.0.4/32 200.0.0.2 nolabel/19

R5#sh ip bgp vpnv4 all

R5#

Thanks,
Vignesh
