BGP route distinguisher not working

[ChinmayaAgarwal]

Description

I have two VRFs vrf1 and dummy_vrf1, and i want to import routes learned in each vrf to the other one. But when I try the below config, I see the learned routes in their respective VRFs but not imported to other one. Also, I don't see rd and rt config being applied anywhere in the vtysh cli.

Version

FRRouting 8.0.1

How to reproduce

I have below config for the same:-

router bgp 65001 vrf dummy_vrf_1
 bgp router-id 192.168.251.124
 no bgp network import-check
 neighbor 24.2.1.102 remote-as 65001
 neighbor 2001:24:2:1::102 remote-as 65001
 !
 address-family ipv4 unicast
  neighbor 24.2.1.102 soft-reconfiguration inbound
  rd vpn export 65001:100
  rt vpn import 65001:100 65001:200
  rt vpn export 65001:100
  export vpn
  import vpn
 exit-address-family
 !
 address-family ipv6 unicast
  neighbor 2001:24:2:1::102 activate
  neighbor 2001:24:2:1::102 soft-reconfiguration inbound
 exit-address-family
!
router bgp 65001 vrf vrf_1
 bgp router-id 192.168.251.124
 no bgp network import-check
 neighbor 37.2.1.102 remote-as 65001
 neighbor 2001:37:2:1::102 remote-as 65001
 !
 address-family ipv4 unicast
  network 24.1.1.0/24
  network 48.1.1.0/24
  redistribute kernel
  neighbor 37.2.1.102 soft-reconfiguration inbound
  rd vpn export 65001:200
  rt vpn import 65001:200 65001:100
  rt vpn export 65001:200
  export vpn
  import vpn
 exit-address-family
 !
 address-family ipv6 unicast
  network 2001:24:1:1::/64
  network 2001:48:1:1::/64
  neighbor 2001:37:2:1::102 activate
  neighbor 2001:37:2:1::102 soft-reconfiguration inbound
 exit-address-family
!

Expected behavior

vtysh cli does not show any route distinguisher config:-

j3chysr01stg06# show bgp vrf er_vrf_1 ipv4 vpn
No BGP prefixes displayed, 0 exist
j3chysr01stg06#

Actual behavior

Ideally I should be seeing routes learned in vrf1 being imported to dummy_vrf1 and vice versa.

Before spending the time digging if this is a real issue or not, could you verify if it's still the problem on the latest versions (9.1, 10.0, or even master)?
