[FROG] import vrf works in running config, but not after write mem and frr restart

[0xbabaf00l]

Hi list,

I'm trying to import routes from one VRF into my default VRF.

This is my sample config:

debian# show running-config
Building configuration...

Current configuration:
!
frr version 7.4
frr defaults traditional
hostname debian
log syslog informational
no ip forwarding
no ipv6 forwarding
service integrated-vtysh-config
!
router bgp 11111
 !
 address-family ipv4 unicast
  network 1.1.1.0/24
 exit-address-family
!
router bgp 22222 vrf red
 !
 address-family ipv4 unicast
  network 2.2.2.0/24
 exit-address-family
!
line vty
!
end


Now I add the import:

debian# conf t
debian(config)# router bgp 11111
debian(config-router)# address-family ipv4 unicast
debian(config-router-af)# import vrf red
debian(config-router-af)# end


Everything works fine. ‘show running-configuration’ shows the correct config.

Then I save the config and restart frr:

debian# write mem
Note: this version of vtysh never writes vtysh.conf
Building Configuration...
Integrated configuration saved to /etc/frr/frr.conf
[OK]
debian# exit
root at debian:~# systemctl restart frr
root at debian:~# vtysh

Hello, this is FRRouting (version 7.4).

debian# sh ru
Building configuration...

Current configuration:
!
frr version 7.4
frr defaults traditional
hostname debian
log syslog informational
no ip forwarding
no ipv6 forwarding
service integrated-vtysh-config
!
router bgp 11111
 !
 address-family ipv4 unicast
  network 1.1.1.0/24
  import vrf red
 exit-address-family
!
router bgp 11111 vrf red
!
line vty
!
end


Why is the router bgp 22222 vrf red block now missing?

As I said, this configuration worked fine until I saved it and restarted frr.


Cheers,
Sascha
