Cisco Asa 5515 OSPF over IPSEC VPN Tunnel

ifabrizio
Level 1
Level 1

Dear All,

 

I have two new Asa 5515 IOS version 9.2(2)4, I have setup a VPN tunnel, and it is established.

Firewall A:

 

Active SA: 1
    Rekey SA: 0 (A tunnel will report 1 Active and 1 Rekey SA during rekey)
Total IKE SA: 1

1   IKE Peer: 37.78.67.67
    Type    : L2L             Role    : responder
    Rekey   : no              State   : MM_ACTIVE

Firewall B:

IKEv1 SAs:

   Active SA: 1
    Rekey SA: 0 (A tunnel will report 1 Active and 1 Rekey SA during rekey)
Total IKE SA: 1

1   IKE Peer: 187.114.235.253
    Type    : L2L             Role    : initiator
    Rekey   : no              State   : MM_ACTIVE

 

 

Then I have configured OSPF on both the Firewall, and the OSPF neighbors see each other:

Firewall A:

Neighbor ID     Pri   State           Dead Time   Address         Interface
 37.98.67.67      0   FULL/  -        0:00:39    37.98.67.67     outside

router ospf 113
 router-id 187.114.235.253  
 network 37.98.67.64 255.255.255.248 area 113
 network 172.26.146.0 255.255.255.0 area 113
 network 187.114.235.248 255.255.255.248 area 113
 area 113 authentication
 neighbor 37.98.67.67  interface outside
 log-adj-changes
 redistribute connected subnets
 redistribute static subnets
 distribute-list ospf out static

Firewall B:

Neighbor ID     Pri   State           Dead Time   Address         Interface
187.114.235.253   1   FULL/  -        0:00:38     187.114.235.253 outside

router ospf 113
 router-id 37.98.67.67     
 network 37.98.67.64 255.255.255.248 area 113
 network 172.26.0.0 255.255.252.0 area 113
 network 187.114.235.248 255.255.255.248 area 113
 area 113 authentication
 neighbor 187.114.235.253   interface outside
 log-adj-changes
 redistribute connected subnets
 redistribute static subnets

If I try to add some static routes on both the firewalls I can see the new route in ospf database, but not in the routing table.

I turned on the ospf debug, and I got this error:

 

OSPF-RIB-GLOBAL: Skip path for  X.X.X.X not on subnet of outside

 

What it means?

I have the same config on two 5505 IOS 8.4 that works well, without any error.

 

Best regards,

 

Igor.
