Try this
On the G0/2
ip address 213.162.233.109 255.255.255.252
ip address 213.162.236.1 255.255.255.240 sec

That should do the trick

This was the setup :

On router 1 :
interface GigabitEthernet0/2
 ip address 213.162.233.109 255.255.255.252 secondary
 ip address 213.162.236.1 255.255.255.240

router ospf 1
 router-id 213.162.236.1
 log-adjacency-changes
 passive-interface default
 no passive-interface GigabitEthernet0/2
 network 213.162.236.0 0.0.0.15 area 0
 network 213.162.238.108 0.0.0.3 area 0
 default-information originate always

On router 2 :

Interface FastEthernet0/0
 Ip address 213.162.233.110 255.255.255.252
 
router ospf 1
 router-id 213.162.233.110
 log-adjacency-changes
 network 213.162.238.108 0.0.0.3 area 0

The debug said on router 1 :

Jul 14 14:45:26: OSPF: Send hello to 224.0.0.5 area 0 on GigabitEthernet0/2
from 213.162.236.1

Jul 14 14:45:28: OSPF: Rcv pkt from 213.162.233.110, GigabitEthernet0/2,
area 0.0.0.0 : src not on the same network

Then I tried on both routers to set :

Ip ospf network point-to-point

On both interfaces... All connection from router 1 to router two went down
for some reason..? I am not sure what happened there.. This sould not bring
the link down, should it?

The secondary Address is specified in a Network OSPF Command? The OSPF
network command for that secondary address should be in the same area as the
network for the primary address, if not assigned to the same area will not
get advertised

Adjacency will never be formed with an IP Secondary Address.

I am trying to get ospf to peer between two routers... On router 1 I have
enabled ospf for a secondary address on the interface..

 

The logs say :

 

Jul 14 14:45:26: OSPF: Send hello to 224.0.0.5 area 0 on GigabitEthernet0/2
from 213.162.236.1

Jul 14 14:45:28: OSPF: Rcv pkt from 213.162.233.110, GigabitEthernet0/2,
area 0.0.0.0 : src not on the same network

 

Does this mean that it want allow me to peer on secondary addresses?

 

And, is there a workaround for this?

 

Jens
