I tried in FRR4.0, got error:
ASW-7001(config-router)# router bgp 65021
ASW-7001(config-router)# add ipv4 vpn 
ASW-7001(config-router-af)# neighbor 11.11.11.2 activate      
ASW-7001(config-router-af)# exit
ASW-7001(config-router)#  vrf-policy cust1
% Unknown command.
ASW-7001(config-router)#

It looks like this “vpn-policy” was introduced in FRR5.0, which I am not in.


Even for 5.0, if i want to configure TWO VRFs (as shown in my IOX configuration). In FRR, do I have to configure 2 BGP instances, and each one has its own vpn-policy, like:

router bgp 6552 vrf red <======== BGP instance 1
vpn-policy ipv4
    label 1041
    rd 10:41
    rt both 51:100
   exit


router bop 6552 vrf blue <===== BGP instance 2
   vpn-policy ipv4
    label 1042
    rd 10:42
    rt both 52:100
   exit


Can I just configure one BGP instance, and have 2 vpn-policy, one for red, one for blue,  under the same BGP instance?


thanks

Thanks for your replies, I actually went through the document/examples for FRR 5.0, but wondering if I could do L3VPN on 4.0, without VRF leaking.

In order to do that, I need to attach RD/RT to each VRF, so looking for configuration to configure RD/RT in FRR4.0.

Hi,

Some good examples can also be found in topotest, e.g.,

https://github.com/FRRouting/frr/blob/master/tests/topotests/bgp_l3vpn_to_bgp_vrf/r4/bgpd.conf

but this uses the current RD/RT syntax but I'm unsure of the syntax for 4.0.

Looking back, I suggest trying the following the example from a correspondingly old version of topotest:

https://github.com/FRRouting/topotests/blob/98ced3d021ec0bf03607dc5e2922673f2c4b15d2/bgp_l3vpn_to_bgp_vrf/r4/bgpd.conf

Hello,

I am trying to migrate from IOX to FRR4.0.   I have a simple configuration of 2 VRFs: red and blue. No VRF route leaking is needed.

I know VRF route leaking was added to FRR5.0. But since I don’t do that.  Can FRR4.0 be used to

- Configure 2 VRFs for routes,  attach different RD/RT to routes, and advertise routes into corresponding VPNs with FRR4.0?
- Any configuration examples?


Below is the current Cisco configuration.

ip vrf red
 rd 100:101
 route-target export 200:101
 route-target import 200:101
!
ip vrf blue
 rd 100:201
 route-target export 200:201
 route-target import 200:201
!
interface Loopback101
ip vrf forwarding red
!
interface Loopback102
 ip vrf forwarding blue
!
router bgp 100
 neighbor 10.10.10.2 remote-as 200
 neighbor 10.10.10.2 update-source Loopback0
!
 address-family vpnv4
  neighbor 10.10.10.2 activate
  neighbor 10.10.10.2 send-community both
  exit-address-family
!
 address-family ipv4 vrf red
 redistribute connected
 exit-address-family
!
 address-family ipv4 vrf blue
 redistribute connected
 exit-address-family
