Hi Guy
I have one ASR9K peering with one Nexus7700 via IBGP
On each device i have VRF A with same route-target import and export but RD is diffirent
Two device establish IBGP successfull, ASR9K can receive route in VRFA from Nexus but Nexus can't receive route in VRFA from ASR9K
when show bgp vpnv4 all on Nexus, and Nexus show it was received VPNv4 route from ASR9K
I don't know why
ASR9K
vrf A
address-family ipv4 un
import route-target 79:79
export route-target 79:79
!
int loopback 1
vrf A
ip address 9.9.9.9/32
!
router bgp 1
router-id 99.99.99.99
add ipv4 un
add vpnv4 un
neighbor 77.77.77.77
remote-as 1
update-source lo0
add ipv4 un
add vpnv4 un
vrf A
rd 9:9
add ipv4 un
network 9.9.9.9/32
Nexus7700
vrf context A
rd 7:7
address-family ipv4 un
route-target import both 79:79
!
int loopback 1
vrf member A
ip address 7.7.7.7/32
!
router bgp 1
router-id 77.77.77.77
add ipv4 un
add vpnv4 un
neighbor 99.99.99.99 remote-as 1
update-source lo0
add ipv4 un
add vpnv4 un
vrf A
add ipv4 un
network 7.7.7.7/32
ASR9K can receive 7.7.7.7 from vrf A when show route vrf A
Nexus can receive 9.9.9.9 when show bgp vpnv4 all but can't receive route from VRF A when show ip route vrf A
Please help me fix this issue

Hello
Could you please share the below output from Nexus -
- show bgp vrf <vrf-name> ipv4 unicast
- show ip route vrf <vrf-name>
- show bgp vpnv4 unicast
- show feature | in enabled
From IOS XR:
- show bgp vpnv4 unicast neighbor <Nexus-IP> advertised-routes
