Dear Community Members,
I would like to ask your help in OSPF configuration, because I'm stuck and I don't know why it does not work.
So I have RouterA and RouterB connected to each other with a Layer3 LACP port channel, the link is up, and can ping each others IP (from /30 subnet). Each router has a vrf called: intvlans and two Layer3 vlan interfaces. One of them will propagate (announce?) 11.22.33.0/24 via OSPF and vrf for a local subnet 192.168.105.0/24 The relevant configuration:
RouterA:
ip vrf intvlans
!
interface Port-channel18
ip address 1.1.1.1 255.255.255.252
!
interface Vlan15
ip address 11.22.33.44 255.255.255.0
!
interface Vlan105
ip vrf forwarding intvlans
ip address 192.168.105.1 255.255.255.0
no ip redirects
no ip proxy-arp
RouterB:
ip vrf intvlans
!
interface Port-channel1
ip address 1.1.1.2 255.255.255.252
!
interface Vlan15
ip address 11.22.33.45 255.255.255.0
!
interface Vlan105
ip vrf forwarding intvlans
ip address 192.168.105.2 255.255.255.0
Please note that Vlan15 Layer3 interface does not belongs to (any) vrf. The relevant OSPF configuration is:
RouterA:
router ospf 2 vrf intvlans
router-id 192.168.105.1
log-adjacency-changes
capability vrf-lite
network 192.168.105.0 0.0.0.255 area 0
!
router ospf 1
router-id 11.22.33.44
log-adjacency-changes
network 11.22.33.0 0.0.0.255 area 0
RouterB:
router ospf 2 vrf intvlans
router-id 192.168.105.2
log-adjacency-changes
capability vrf-lite
network 192.168.105.0 0.0.0.255 area 0
!
router ospf 1
router-id 11.22.33.45
log-adjacency-changes
network 11.22.33.0 0.0.0.255 area 0
For the OSPF process 1 (without vrf), it works fine, there is no problems at all. In both RouterA and RouterB for show ip route ospf 1 I see the routes (11.22.33.0/24).
The problem is that the OSPF process 2, it didn't work. In both RouterA and RouterB for show ip route vrf intvlans ospf I see nothing.
RouterA outpur for show ip ospf 2 database:
OSPF Router with ID (192.168.105.1) (Process ID 2)

RouterB outpur for show ip ospf 2 database:

RouterA and RouterB (same output) for show ip vrf intvlans:
Name Default RD Interfaces
intvlans <not set> Vl105
Any help to figure out what is wrong would be much appreciated.
