IOS XRv redistribute connected or OSPF

neo2000 · ‎02-18-2019

Hi Guys,

Scenerio is

(XRv) (C7200 - virtual) (XRv)

R1----------R2------------------R3

I'm testing L3VPN in EVE-NG.

I've created a very simple topology and configuration, MPLS, OSPF and BGP is working normally, but when I'm trying to redistribute connected or ospf 2 route-s to my vrf (hanssolo), I can't see the redistributed routes (neither OSPF, neither connected) in vrf routing table.

Do you have an idea or solution for this problem?

Is my configuration ok or I missed something? Or some XRv bug?

Config:

hostname R1

I wonder about having both OSPF processes use the same router ID. I would suggest making each router ID unique. Also I suggest under router ospf add to the redistribute command the parameter subnets.

Hi Rick,

Thanks for your answer. I made some change in configuration, for example R1:

router bgp 1
address-family ipv4 unicast
!
address-family vpnv4 unicast
!
neighbor 3.3.3.3
remote-as 1
update-source Loopback0
address-family ipv4 unicast
!
!
vrf hanssolo
rd 1:4
address-family ipv4 unicast
redistribute ospf 2
!
!

router ospf 2
vrf hanssolo
router-id 192.168.1.1
redistribute bgp 1
area 0
interface GigabitEthernet0/0/0/1
passive disable

R3 config is similar, but situation is not mutch better. I dont understand exactly what did you mean 'redistribute command the parameter subnets', because in XRv there aren't network command in ospf process (i can just change network type).

ps. Just for testing, I made this configuration with IOS and IOS-XE, and here redistributing working perfectly. So I think, I've missed someting from bgp or ospf configuration on XRv, or there are some kind of bug, and the redistribution will not work anyway.

Best regards,
